Answer 1

Answer:

D. CF₄

Explanation:

The compound with this molecular geometry is Carbon tetrafluoride (CF₄)

Carbon tetrafluoride (CF₄) also known as Tetrafluoromethane, is known to be the simplest perfluorocarbon. The compound, tetrafluoromethane is the hydrocarbon methane has been perfluorinated. It useful as a refrigerant but known to be a greenhouse gas. Due to the nature of the carbon-flourine bond, it has very high bonding strength. Its bonds are known to be the strongest single bonds in organic chemistry.

Option D is the correct answer.

Find the mass of sodium required to reduce 6.58 L of hydrogen gas at 32°C and 895 mm, when sodium reacts with hydrochloric acid. (Hint: you first need to write a balanced chemical equation.)

Answers

Answer:

Mass = 14.72 g

Explanation:

Given data:

Volume of hydrogen = 6.58 L

Temperature of gas = 32°C (32+273 = 305 k)

Pressure of gas = 895 mmHg (895/760 = 1.2 atm)

Mass of sodium required = ?

Solution:

Chemical equation:

2HCl + 2Na → 2NaCl + H₂

Number of moles of hydrogen:

PV = nRT

1.2 atm × 6.58 L = n× 0.0821 atm.L/mol.K×305 K

7.9 atm.L = n× 25.0 atm.L/mol

n = 7.9 atm.L / 25.0 atm.L/mol

n = 0.32 mol

Now we will compare the moles of hydrogen with sodium.

H₂ : Na

1 : 2

0.32 : 2/1×0.32 = 0.64 mol

Mass of sodium:

Mass = number of moles × molar mass

Mass = 0.64 mol × 23 g/mol

Mass = 14.72 g

can some one please help me with this question with the steps please, thanks in advance

The molecular formula for Hydrocarbon = C₄H₁₀

Further explanation:

Given

50 ml hydrocarbon

200 ml CO₂

250 ml H₂O

Required

The molecular formula of Hydrocarbon

Solution

From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles

So moles Hydrocarbon : CO₂ : H₂O = 50 ml : 200 ml : 250 ml = 1 : 4 : 5

mol C in 1 mol CO₂=1, and for 4 moles CO₂ there are 4 moles C

mol H in 1 mol H₂O =2, and for 5 moles H₂O there are 10 moles H

So mol ratio C : H in compound = C₄H₁₀

period number used in a sentence

Answer:

Explanation:

Why do the voices sound different when you listen to them through the wall?
Sound waves travel at different speeds when traveling through different
materials
Sound waves change frequency over long distances
Sound waves do not pass through solid materials
Your ear processes sound differently when it goes through a solid.

Answers

Answer:

Sound waves travel at different speeds when traveling through different materials

Explanation:

This is because in water the particles are more closely packed together, therefore making the sound travel faster and sound louder. The opposite is the same for air.

How is pressure proportional to volume?

Answers

Answer:

When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since P and V are inversely proportional, a graph of 1/P vs. V is linear.

Explanation:

Answer:

Volume and Pressure: Boyle's Law

Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure. In fact, if the volume increases by a certain factor, the pressure decreases by the same factor, and vice versa.
