To determine how much of solution A would be needed to generate the electrical energy used daily in the home

we need to calculate the ratio of the energy released by fusion of hydrogen to the electrical energy used daily.

Energy ratio = Energy released by fusion of hydrogen / Electrical energy used daily

Energy ratio = (8.4 x 10^12) / (3 x 10^8)

To simplify the calculation, we can convert the values to scientific notation with the same exponent:

Energy ratio = (8.4 / 3) x (10^12 / 10^8)

Energy ratio = 2.8 x 10^4

This means that for every unit of electrical energy used daily in the home, we would need 2.8 x 10^4 units of solution A to generate that energy.

Therefore, to generate the electrical energy used daily in the home, we would need 2.8 x 10^4 liters of solution A.

Answer:

D

Explanation:

Answer: The quantity of solute particles in a solution determines its colloidal qualities, not its chemical composition. Boiling point elevation and freezing point depression are two widely researched colligative features.

Explanation: Sugar is a non-electrolyte solute that does not separate into ions in water (C12H22O11). The amount of dissolved sucrose molecules affect the colloidal characteristics of the substance.

Urea, or CO (NH2)2, is a solute that quickly dissociates into ions in water. Compared to non-electrolytes like sucrose, it adds more particles to the solution, which has a greater impact on the colligative qualities.

Answer:

5.77% Error.

Explanation:

Given an experimental value of 275 g , and a theoretical value of 260 g, the percent error can be found using the equation:

\(\% \: error \: = \frac{ |theoretical \: value \: - \: experimental \: value | }{theoretical \: value} \times 100\)

% Error = ( | 260 - 275 | / 260 ) × 100 = ( | - 15 | / 260 ) × 100 = ( 15 / 260 ) × 100 = 1500/260 = 300 / 52 = 5.769230769230.. ≈ 5.77%

To determine the value of ∆Hrxn for the reaction, we can use the equation:

∆Hrxn = q / n

where q is the heat of the reaction, n is the number of moles of reactants, and ∆Hrxn is the change in enthalpy of the reaction.

We can use the equation for calculating heat:

q = mc∆T

where q is the heat, m is the mass of the solution, c is the specific heat of the substance, and ∆T is the change in temperature.

The mass of the solution is equal to the volume of the solution times the density:

m = V * d

Plugging this equation into the equation for calculating heat, we get:

q = (V * d) * c * ∆T

We can use the values given in the problem to solve for q:

q = (0.200 L * 1.00 g/mL) * (4.18 J/g°C) * (23.48°C - 22.15°C)

q = 4.32 J

To determine the value of ∆Hrxn, we need to know the number of moles of reactants. The concentration of the HCl solution is 0.2 M, so the number of moles of HCl is:

n = (0.200 L) * (0.200 mol/L) = 0.040 mol

Plugging this value into the equation for ∆Hrxn, we get:

∆Hrxn = q / n = (4.32 J) / (0.040 mol) = 108 J/mol

Therefore,  ∆Hrxn=108 J/mol

an apple is best described as a heterogeneous mixture.

The phrase that best describes an apple is heterogenous mixture because it is made up of a different materials.

A mixture is combination of different components that can be uniform or dispersed and homogenous or heterogenous.  A homogenous mixture is the one in which the two or more components are dissolved together to form only one phase.

A heterogenous mixture is composed different phases with uniform or irregular arrangement of materials. Heterogenous mixtures look like a nonseparated random particles which are clearly distinguishable by eyes.

Apple is not a compound but is a mixture made up of different components such as water, pulp, seeds, pigments etc. and each forms their own phases.

There are c. 1.20 x \(10^{24}\) atoms in 2 moles of sodium.

To determine the number of sodium atoms in 2 moles of sodium, we need to use Avogadro's number, which states that one mole of any substance contains 6.02 x \(10^{23}\) particles. Since we have 2 moles of sodium, we can multiply 2 by Avogadro's number to find the total number of sodium atoms. The calculation would be: 2 moles * 6.02 x \(10^{23}\) atoms/mole = 1.20 x \(10^{24}\) atoms.

Therefore, the correct option is c. 1.20 x \(10^{24}\). This represents the approximate number of sodium atoms present in 2 moles of sodium.

The statement among the available options that describes the result of the study is that less than 50% of the people never felt phantom pain. Option 2.

In order to interpret the data and find the best description of the outcome of the experiment, the response needs to be grouped into 2 from the 3 available responses.

Since those that phantom pain sometimes and always belong to the same category, the respondents can be summed up into one:

Number of those that sometimes feel phantom pain = 534

Number of those that always feel phantom pain = 193

Total number of people that feel phantom pain = 534 + 193

                                                                                = 727 people

Number of people that never feel phantom pain = 183

Total number of respondents in the experiment = 183 + 534 + 193

                                                                                = 910 people

Percentage of respondents that felt phantom pain = 727/910 x 100

                                                                                     = 79.89%

Percentage of people that never felt phantom pain = 183/910 x 100

                                                                                      = 20.11%

Percentage of people that felt phantom pain all the time = 193/910 x 100

                                                                                      = 21.21%

Thus, the statement that correctly describes the outcome of the experiment of all the statements is that less than 50% never felt phantom pain.

Explanation:

During photosynthesis, plants intake carbon dioxide from the air and releases oxygen. Thus, they are providing enough oxygen available for humans to breath.

Photosynthesis is a bio-chemical process by which green plants produces chemical energy with the aid of light energy absorbed by chlorophyll. Photosynthetic reaction is the combination of carbon dioxide and water giving molecular oxygen and glucose.

Through photosynthesis, the amount ox oxygen and carbon dioxide in the atmosphere is balanced. This balancing cycle involves respiration of animals also.

The carbon dioxide that we exhale are up taken by plants and converts to oxygen gas. This makes sufficient oxygen for all animals to breath. Therefore, photosynthesis is a stage in carbon cycle and oxygen cycle.

When 10.0 ml of iron sulphate solution is added to 10.0 ml of iron nitrate the resulting concentration of fe2 and fe3 are b. 0.1 M and 0.1 M, respectively.

First, let's calculate the moles of Fe2+ and Fe3+ ions present in their respective solutions before mixing.
Moles of Fe2+ in iron(II) sulfate solution = (0.2 M)(0.010 L) = 0.002 moles
Moles of Fe3+ in iron(III) nitrate solution = (0.2 M)(0.010 L) = 0.002 moles

Now, combine the solutions by adding the 10.0 mL of iron(II) sulfate solution to the 10.0 mL of iron(III) nitrate solution.

Calculate the total volume of the mixed solution: 10.0 mL + 10.0 mL = 20.0 mL = 0.020 L

Determine the new concentrations of Fe2+ and Fe3+ ions in the mixed solution:
- Concentration of Fe2+ = moles of Fe2+ / total volume = 0.002 moles / 0.020 L = 0.1 M
- Concentration of Fe3+ = moles of Fe3+ / total volume = 0.002 moles / 0.020 L = 0.1 M

So, the resulting concentrations of Fe2+ and Fe3+ in the mixed solution are 0.1 M and 0.1 M, respectively.

An explanation for a natural occurrence is provided by a hypothesis, which is supported by observation and testing.

A hypothesis is a well-informed prediction based on specific data that serves as the basis for more research.

Many of them dismiss evolution as "simply a hypothesis," in contrast to gravity, which must exist because it is a law. In the scientific community, the terms "theory," "facts," "laws," and "hypothesis" have extremely particular meanings that don't quite correspond to the ones we use in ordinary language. A testable hypothesis is a speculative explanation for an observable. It serves as a springboard for additional explanation.
