Answer:

18 L

Explanation:

boyles law

P1V1 = P2V2

V2 = P1V1/P2

V2 = (.9 * 4)/.2

V2 = 18

This question is based on Boyle's law as temperature is constant. Boyle's law is derived from ideal gas equation only at constant temperature. Therefore, the new pressure is  18L.

Boyle's law is a law which states that at constant temperature, the pressure that is exerted by an ideal gas on the walls of the container is inversely proportional to the volume occupied that gas.

Ideal gas is a gas where there is no forces of attraction or forces of repulsion between the particles . The volume of container is equal to the volume occupied by the gas.

Mathematically, Boyle's law can be written as

P₁V₁ = P₂V₂

P₁=initial pressure

P₂=final pressure

V₁ = initial volume

V₂=final pressure

V₂ = P₁V₁/P₂

V₂ = (0.9 × 4)/0.2

V₂  = 18L

Therefore, the new volume is  18L.

5.1 grams of Cl2 is calculated as 1.610 L.  As all the gases that behave ideally have the same number density, they will also have the same molar volume.

Molar volume of a substance is the volume occupied by one mole of  substance at given temperature and pressure. It is equal to the molecular mass of the substance divided by its density at the given temperature and pressure: It has SI unit of cubic meters per mole.

Given 5.1 grams of Cl2

As molar mass of Cl2 = 70.906 g/mol

So, moles = 5.1/70.906

= 0.0719 mol

Volume= moles of cl2 * molar volume of cl2

As molar volume of cl2 = 22.40 L

So, Volume = 0.0719 * 22.40

Answer:

14.5g of CO₂ are produced

Explanation:

The reaction of octane with oxygen is:

C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O

Where 1 mole of octane (Molar mass: 114.23g/mol) reacts with 25/2 moles of O₂ (Molar mass 32g/mol) to produce 8 moles of CO₂ and 9 moles of water.

When 21.0 g of octane is burned with 19.0 g of oxygen gas you need to find limiting reactant to find how many moles of products are formed:

Octane: 21.0g ₓ (1mol / 114.23g) = 0.184 moles octane

Oxygen: 19.0g ₓ (1 mol / 32g) = 0.594 moles oxygen

For a complete reaction of 0.184 moles of octane you will need:

0.184 moles C₈H₁₈ ₓ (25/2 moles O₂ / 1 mole C₈H₁₈) = 2.3 moles of oxygen

As you have just 0.594 moles of oxygen, Oxygen is limiting reactant.

Based on chemical equation, 25/2 of O₂ produce 8 moles of CO₂, that means theoretical yield of CO₂ with 0.594 moles of O₂ is:

0.594 moles O₂ ₓ (8 moles CO₂ / 25/2 moles O₂) = 0.380 moles of CO₂

But, as yield of products is 87%, moles produced of CO₂ are:

0.380 moles of CO₂ ₓ 87% = 0.331 moles CO₂ are produced.

As molar mass of CO₂ is 44g/mol, mass of CO₂ in 0.331 moles is:

0.331 moles CO₂ ₓ (44g / mol) =

Answer:

Carbon has 4 valence electrons and Chlorine has 7 valence electrons. The bonding between the atoms is due to electronegativity difference. The electronegativity of carbon is 2.5 compared to chlorine which is 3.1, so they will bond by sharing the electron pair (valance electron) from each atom in a covalent bond. In addition, Carbon is more electronegative than Chlorine, which means that it takes less energy to remove an electron from Carbon than from Chlorine. This makes it easier for the electrons to be shared between them (since there is less energy required to share an electron).

We can see that an atom with 14 protons, 14 neutrons, and 16 electrons is unstable, and has a -2 charge.

So the correct option is the third one.

An atom with 14 protons, 14 neutrons, and 16 electrons is not stable. The number of protons in an atom, also known as its atomic number, determines its element and its chemical properties. In this case, the atom has 14 protons, which corresponds to the element silicon (Si) on the periodic table.

For an atom to be stable, it should have a balanced number of protons and electrons. Electrons are negatively charged particles that orbit the nucleus of an atom in energy levels or electron shells. The number of electrons in a stable atom should be equal to the number of protons, resulting in a neutral charge overall.

In this case, the atom has 14 protons and 16 electrons, which means it has two more electrons than protons, resulting in a net charge of -2. This is an example of an ion.

The partial pressure of \(N_2\)is 165.6 kPa and the partial pressure of \(H_2\)is 434.4 kPa.

To calculate the partial pressures of \(H_2\)and \(N_2\)in the 10dmcube container, we need to use the ideal gas law equation, which states that the pressure of a gas is directly proportional to its number of moles and temperature, and inversely proportional to its volume.

First, we need to calculate the number of moles for each gas. Since we are given the volume of each gas and the volume of the container, we can use the formula:

Number of moles = Volume / Molar volume

The molar volume is the volume occupied by one mole of a gas at a given temperature and pressure. At standard temperature and pressure (STP), the molar volume is 22.4 L/mol.

For \(N_2\), the number of moles is 2 dmcube / 22.4 L/mol = 0.089 mol
For \(H_2\), the number of moles is 5 dmcube / 22.4 L/mol = 0.223 mol

Next, we can calculate the partial pressures of each gas using the formula:

Partial pressure = (Number of moles / Total number of moles) * Total pressure

The total pressure is the sum of the pressures of each gas:

Total pressure = Pressure of N2 + Pressure of \(H_2\)

Given that the pressure of N2 is 100 kPa and the pressure of \(H_2\)is 500 kPa, we have:

Total pressure = 100 kPa + 500 kPa = 600 kPa

Now we can calculate the partial pressure of \(N_2\):

Partial pressure of \(N_2\)= (0.089 mol / (0.089 mol + 0.223 mol)) * 600 kPa = 165.6 kPa

Similarly, we can calculate the partial pressure of \(H_2\):

Partial pressure of H2 = (0.223 mol / (0.089 mol + 0.223 mol)) * 600 kPa = 434.4 kPa

Therefore, the partial pressure of \(N_2\)is 165.6 kPa and the partial pressure of \(H_2\)is 434.4 kPa.

Types of luminous flames:

1. Yellow Luminous Flame

2. Smoky Luminous Flame

3. Orange Luminous Flame

4. Blue Luminous Flame

Luminous flames are characterized by their visible glow, which is caused by the incomplete combustion of fuel. The presence of soot particles in the flame causes the emission of light. There are different types of luminous flames, which can be classified based on their fuel composition and burning conditions. Here are some common types of luminous flames:

1. Yellow Luminous Flame: This is the most common type of luminous flame, often seen in open fires, candles, and gas stoves. It appears yellow due to the presence of soot particles in the flame. Yellow flames indicate incomplete combustion of hydrocarbon fuels, such as methane, propane, or natural gas. The high carbon content in these fuels leads to the formation of soot, which emits visible light.

2. Smoky Luminous Flame: This type of flame is characterized by a significant amount of black smoke and soot production. It is commonly observed in poorly adjusted or malfunctioning burners or engines. The excessive presence of unburned fuel in the flame results in incomplete combustion and the emission of dark smoke particles.

3. Orange Luminous Flame: An orange flame indicates a higher combustion temperature compared to a yellow flame. It is often seen in more efficient burners or when burning fuels with a higher carbon content, such as oil or diesel. The higher temperature helps in burning more of the carbon particles, reducing the amount of soot and making the flame appear less yellow.

4. Blue Luminous Flame: A blue flame is typically associated with complete combustion. It indicates efficient burning of fuel, resulting in minimal soot formation. Blue flames are commonly observed in gas burners or Bunsen burners. The blue color is a result of the combustion of gases, such as methane, in the presence of sufficient oxygen.

It's important to note that the luminosity of a flame can vary depending on factors such as fuel-air mixture, combustion temperature, and the presence of impurities. Achieving complete combustion and minimizing the production of soot is desirable for efficient and cleaner burning processes.

The volume of Na2SiO3 that can react with 0.8000 grams of HF at STP is approximately 0.9663 liters.

To calculate the volume of Na2SiO3 (sodium silicate) that can react with 0.8000 grams of HF (hydrofluoric acid) at standard temperature and pressure (STP), we need to use stoichiometry and the ideal gas law.

Write the balanced chemical equation for the reaction between Na2SiO3 and HF:

Na2SiO3 + 6HF → Na2SiF6 + 3H2O

Determine the molar mass of HF:

The molar mass of HF is:

H (hydrogen) = 1.008 g/mol

F (fluorine) = 18.998 g/mol

So, the molar mass of HF = 1.008 + 18.998 = 20.006 g/mol

Convert the given mass of HF to moles:

Mass of HF = 0.8000 g

Molar mass of HF = 20.006 g/mol

Moles of HF = Mass of HF / Molar mass of HF

Moles of HF = 0.8000 g / 20.006 g/mol

Moles of HF = 0.03999 mol (rounded to five decimal places)

Use the stoichiometry of the balanced equation to determine the molar ratio between Na2SiO3 and HF:

From the balanced equation, we can see that 6 moles of HF react with 1 mole of Na2SiO3.

Use the ideal gas law to calculate the volume of Na2SiO3 at STP:

The ideal gas law is given by:

PV = nRT

where:

P = Pressure (at STP, P = 1 atm)

V = Volume

n = Number of moles of gas (in this case, moles of Na2SiO3)

R = Ideal gas constant (0.0821 L atm / mol K)

T = Temperature (at STP, T = 273.15 K)

Rearrange the formula to solve for volume (V):

V = nRT / P

Plugging in the values:

n = 0.03999 mol (from step 3)

R = 0.0821 L atm / mol K

T = 273.15 K (at STP)

P = 1 atm (at STP)

V = 0.03999 mol * 0.0821 L atm / mol K * 273.15 K / 1 atm

V = 0.9663 L (rounded to four decimal places)

Exactly 149.6J will raise the temperature of 10.0g of a metal from 25.0C. The specific heat capacity of the metal is 5.984 J/g°C.

The heat capacity of a sample of a substance divided by the mass of the sample yields the specific heat capacity (symbol c), also known as massic heat capacity. Informally, it is the quantity of heat that must be added to one unit of a substance's mass in order to raise its temperature by one unit. The specific heat capacity unit in the SI is the joule per kelvin per kilogram, or Jkg⁻¹K⁻¹. For instance, the specific heat capacity of water is 4184 J kg⁻¹K⁻¹, or the amount of energy needed to raise 1 kilogram of water by 1 K.

The specific heat capacity of the metal can be calculated using the equation Q = m × c ×ΔT.

Q = 149.6J

m = 10.0g

ΔT = (final Temperature - initial Temperature) = (25°C - 0°C) = 25°C

Plugging these values into the equation, we get:

149.6J = 10.0g × c ×25°C

Solving for c, we get:

c =  \(\frac{149.6J}{(10.0g *25C)}\)

c = 5.984 J/g°C

Therefore, the specific heat capacity of the metal is 5.984 J/g°C.
