Which of these statements is one of the conclusions that formed the basis of dalton’s atomic theory?.

Answers

The correct answer is option D.

The statement that formed the basis of Dalton’s atomic theory is atoms are the smallest particles of matter and cannot be divided farther.

In 1808, Dalton presented a theory named atomic theory which suggests that atoms are the smallest particles of an element and it is impossible to divide them further.

According to his theory every element is composed of these tiny particles.

Furthermore, his theory suggests that atoms neither can be divided nor destroyed.

In a particular matter, for example gold, all atoms have similar properties while their mass varies for every single different element.

be sure to answer all parts. give the iupac name for the following compound. ch3ch2ch(ch3)c≡cch2ch3

Answers

The IUPAC name for the given compound is 4-ethyl-2-pentyne.

Here's how to arrive at the name:

First, we number the longest carbon chain that contains the triple bond. In this case, it's a 6-carbon chain:

```

CH3CH2CH(CH3)C≡CCH2CH3

 |   |   |   | |   |

 1   2   3   4 5   6

```

Next, we locate and name the substituents. The chain has two substituents: an ethyl group (CH3CH2-) attached to carbon 4 and a methyl group (-CH3) attached to carbon 3. Since there are two substituents, we need to use the prefixes di- and eth- to indicate their number and location in the chain, respectively:

- The ethyl group is on carbon 4, so it becomes 4-ethyl.

- The methyl group is on carbon 3, so it becomes 3-methyl.

Putting it all together, we get the name:

4-ethyl-3-methyl-2-pentyne. However, we can simplify the name by using the lowest possible numbers for the substituents, giving us the final name:

4-ethyl-2-pentyne.

if 17.6 ml of 0.800 m hcl solution are needed to neutralize 5.00 ml of a household ammonia solution, what is the molar concentration of the ammonia? express your answer with the appropriate units.

Answers

The molar concentration of the household ammonia solution is 2.816 mol/L. To find the molar concentration of the ammonia, we can use the concept of molarity and the neutralization reaction between HCl and ammonia (NH3).

Step 1: Write the balanced chemical equation for the neutralization reaction:
HCl + NH3 → NH4Cl

Step 2: Calculate the moles of HCl used in the reaction:
Moles of HCl = Molarity × Volume = 0.800 mol/L × 17.6 mL × (1 L/1000 mL) = 0.01408 mol

Step 3: Determine the moles of ammonia (NH3) in the reaction. Since the reaction is a 1:1 ratio, the moles of NH3 will be the same as the moles of HCl.
Moles of NH3 = 0.01408 mol

Step 4: Calculate the molar concentration of ammonia (NH3) using the formula:
Molarity of NH3 = Moles of NH3 / Volume of NH3 solution
Molarity of NH3 = 0.01408 mol / (5.00 mL × (1 L/1000 mL)) = 2.816 mol/L

So, the molar concentration of the household ammonia solution is 2.816 mol/L.

If 3grams of sodium reacts with 25 grams of sulfuric acid to form sodium sulfate and 1 gram of hydrogen and no sodium is left after the reaction but 9grams of acid remained unreacted how many grams of sodium sulfate were formed

Answers

The balanced chemical equation for the reaction between sodium and sulfuric acid to form sodium sulfate and hydrogen gas is:

2Na + H2SO4 -> Na2SO4 + 2H2

From the given information, we can see that the reaction is limited by the amount of sodium available, since all of the sodium is used up in the reaction.

Therefore, we can use the amount of sodium to determine the amount of sulfuric acid that reacted and the amount of sodium sulfate that was formed.

1. Calculate the amount of sulfuric acid that reacted:

m(Sulfuric acid) = 25 g - 9 g = 16 g

n(Sulfuric acid) = m(Sulfuric acid) / M(Sulfuric acid) = 16 g / 98.08 g/mol = 0.163 mol

2. Calculate the amount of sodium sulfate formed:

Since the mole ratio of Na to Na2SO4 is 2:1, the number of moles of sodium used is:

n(Na) = m(Na) / M(Na) = 3 g / 22.99 g/mol = 0.1305 mol

The amount of sodium sulfate formed is also 0.1305 mol, since the mole ratio of Na to Na2SO4 is 2:1.

m(Na2SO4) = n(Na2SO4) x M(Na2SO4) = 0.1305 mol x 142.04 g/mol = 18.54 g

Therefore, 18.54 grams of sodium sulfate were formed in the reaction.

A small ammonia plant used 123,000 g of H2 gas per day. Determine the mass of CO2 (in g) that will be released as the H2 is produced. Show all work

Answers

Answer:Main Answer:

The mass of CO2 released in the production of 123,000 g of H2 gas is 265,200 g.

Explanation: From the given equation, we can see that the production of 4 moles of H2 requires the combustion of 1 mole of CH4, resulting in the release of 2 moles of H2O and 1 mole of CO2. The molar mass of H2 is 2 g/mol, and the molar mass of CO2 is 44 g/mol. Therefore, the mass of CO2 released in the production of 123,000 g of H2 is (123,000/2) x (1/4) x 44 = 265,200 g.

sensors detect the concentration of mercaptan molecules in natural gas at various distances from a leaking source. at which location will a sensor det

Answers

Option D is correct because mercaptan is heavier than air, which means it will sink and settle close to the ground where it will mix with air.

As a result, the highest concentration of mercaptan will be found closest to the source, and it will gradually decrease as you move away from the source. Therefore, the sensor placed one meter in front of the source will detect the highest concentration of mercaptan because it is closest to the source.

In general, the concentration of a gas is expected to decrease as one moves away from the source due to gas mixing and dispersion in the surrounding air. However, in this case, the presence of mercaptan molecules can provide some additional information.

Mercaptan is added to natural gas as an odorant to make leaks easier to detect. It has a strong and distinct odour, which is often described as "rotten egg" odour. As a result, sensors designed to detect mercaptan can detect it even at very low concentrations.

If the leak is actively releasing mercaptan, the highest concentration will be closest to the source of the leak. As a result, option D, one metre from the source, is the most likely location to detect the highest concentration of mercaptan. The concentration of mercaptan decreases as one moves away from the source, but it may still be detectable at some distance depending on the sensitivity of the sensor.

What pillar of sustainability is broken by recycling

Answers

The pillar of sustainability broken by recycling electronics in India is environmental sustainability. Implementing a law that restricts electronics recycling to the US would not necessarily be the most effective solution, as it overlooks the complex global dynamics of electronic waste management.

Recycling electronics in India often involves improper disposal methods, such as burning or dismantling without proper safety measures. This leads to environmental pollution, including the release of hazardous substances into the air, soil, and water, thus violating the principle of environmental sustainability.

However, simply mandating that electronics can only be recycled in the US may not be the most optimal solution. Electronic waste is a global issue, and restricting recycling to a single country disregards the fact that electronic products are manufactured and consumed worldwide. A more comprehensive approach to addressing electronic waste would involve international cooperation, strict regulations, and monitoring of recycling practices to ensure they meet environmental standards.

Efforts should focus on improving recycling practices globally, including promoting responsible electronic waste management, developing sustainable recycling infrastructure in multiple countries, and encouraging the adoption of safe and environmentally friendly recycling practices. This approach would foster global sustainability and address the challenges associated with electronic waste disposal more effectively than a geographically limited restriction.

Answers

The amount of energy needed to raise the temperature of 10 g of gold from 30°C to 40°C is 12.9 joules.

To calculate the amount of energy needed to raise the temperature of a substance, we can use the following formula;

Q = m × c × \(Δ_{T}\)

Where Q is the amount of energy (in joules), m is the mass of the substance (in grams), c is the specific heat capacity of the substance (in joules per gram per degree Celsius), and \(Δ_{T}\) is change in temperature (in degrees Celsius).

The specific heat capacity of gold is 0.129 joules per gram per degree Celsius.

Using this information, we can calculate the amount of energy needed to raise the temperature of 10 g of gold from 30°C to 40°C;

Q = 10 g × 0.129 J/g°C × (40°C - 30°C)

Q = 10 g × 0.129 J/g°C × 10°C

Q = 12.9 J

Enter your answer for b in the box below, rounded to three decimals.

Answers

The value of b in the equation \(\( f(t) = 85 \cdot b^t \)\) represents the decay factor of the radioactive substance. To determine the value of \( b \), we can use the information that the half-life of the substance is 21 years.

The half-life of a radioactive substance is the time it takes for half of the substance to decay. In this case, the half-life is 21 years, which means that after 21 years, the amount of the substance remaining will be half of the initial amount.

We can use this information to set up an equation:

\(\(\frac{1}{2} = b^{21}\)\)

To solve for b, we need to take the 21st root of both sides of the equation:

\(\(b = \left(\frac{1}{2}\right)^{\frac{1}{21}}\)\)

Using a calculator, we can evaluate this expression:

\(\(b \approx 0.965\)\)

Therefore, the value of b in the equation \(\( f(t) = 85 \cdot b^t \)\) is approximately 0.965.

Answers

70.9-gram sample of \(Cl_{2}\) gas will occupy Opton C. 22.4 liters at STP.

To determine the volume occupied by the sample of \(Cl_{2}\) (g) at STP, we can use the ideal gas law equation, PV = nRT

where P = pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature.

At STP (Standard Temperature and Pressure), the pressure is 1 atmosphere (atm) and the temperature is 273.15 Kelvin (K).

First, calculate the number of moles of \(Cl_{2}\) (g) using its molar mass. The molar mass  \(Cl_{2}\) is 70.9 grams/mol.

Number of moles (n) = mass (m) / molar mass (M)

n = 70.9 g / 70.9 g/mol

n = 1 mol

Now, we can calculate the volume using the ideal gas law:

V = (nRT) / P

V = (1 mol * 0.0821 L·atm/mol·K * 273.15 K) / 1 atm

V ≈ 22.4 L

Answers

Semicrystalline polymers are opaque because the crystallites scatter light. Option B is correct.

When light passes through a semicrystalline polymer, it encounters regions of ordered crystallites and disordered amorphous regions. The ordered crystallites have a different refractive index compared to the amorphous regions, which causes the light to scatter as it passes through the material. This scattering of light is what makes semicrystalline polymers appear opaque.

In contrast, the amorphous regions of semicrystalline polymers do not absorb light, transmit light, diffract light, or absorb light. Rather, the amorphous regions simply do not have a regular arrangement of atoms and molecules, which means that they do not interact with light in a coherent manner.

whcih of the following amino acid contain nonpolar r group

Answers

Glycine, Alanine, and Leucine are all nonpolar amino acids. Nonpolar amino acids are characterized by having R-groups that are hydrophobic, meaning they do not interact well with water molecules. The correct answer is B.

These R-groups are typically composed of carbon and hydrogen atoms only and lack any significant charge, making them less likely to interact with polar or charged molecules in their environment.

Phenylalanine, Tyrosine, and Tryptophan are aromatic amino acids that have nonpolar R-groups but also contain functional groups that can form hydrogen bonds or interact with other polar molecules. Thus, while they are nonpolar, they are not as hydrophobic as Glycine, Alanine, and Leucine.

Lysine, Arginine, and Histidine are all polar amino acids with charged R-groups that are capable of forming ionic bonds or participating in hydrogen bonding. Serine, Threonine, and Cysteine all have polar R-groups that contain functional groups such as hydroxyl (-OH) or thiol (-SH) groups that can participate in hydrogen bonding or form disulfide bonds.

Answers

Answer:

53295 J or 53kJ

Explanation:

The specific heat of a substance is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree celsius.

The specific heat of water is 4.18 J/g°C. This means that to raise one gram of a sample of water by one degree celsius, 4.18 J of energy is required.

The heat energy (q), required to raise the temperature (ΔT) of a given substance, with a given mass (m) and specific heat capacity (c) is given by the formula;

q= m.c.ΔT

Substituting the data given into the formula, we will have,

- The presence of two signals at 2H indicates the presence of a di-substituted ethylene group (-CH=CH-) in the molecule.
- The signal at 6.71 δ indicates the presence of a hydrogen atom attached to an sp2 hybridized carbon, likely part of the di-substituted ethylene group.
- The signals at 6.27 and 6.36 δ indicate the presence of two hydrogen atoms attached to two separate sp2 hybridized carbon atoms, also part of the di-substituted ethylene group.
- Since there are no other hydrogen atoms present, it can be concluded that the remaining hydrogen atom is attached to the nitrogen atom, completing the structure as shown above.

Based on the given 1H-NMR data for the compound with the chemical formula C8H11N, the structure can be determined as follows:

1. A singlet (s) at 2.34 δ with 6 hydrogens (6H) suggests a CH3 group attached to an electronegative atom, like nitrogen (N). There are two of these groups since 6H are present.
2. A singlet (s) at 6.27 δ with 2 hydrogens (2H) indicates a CH2 group that is part of an aromatic ring.
3. A singlet (s) at 6.36 δ with 1 hydrogen (1H) represents a CH group in the aromatic ring, possibly ortho or para to the CH2 group.
4. A singlet (s) at 6.71 δ with 2 hydrogens (2H) suggests another CH2 group that is part of the aromatic ring and adjacent to the nitrogen atom.

Based on this information, the structure of the compound can be determined as N,N-dimethyl-2,5-dihydroxyaniline. The aromatic ring contains a primary amine (NH2) group with two methyl groups (CH3) attached to the nitrogen atom, and hydroxyl (OH) groups at positions 2 and 5.
