The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation

Bad White [126]

<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>

When 32.5g of carbon is heated with silicone dioxide, 28.8 g of carbon monoxide is produced. What is the percent yield of carbon

Anvisha [2.4K]

Answer:

Percent yield of carbon monoxide is approximately 38%.

Explanation:

Given reaction : C + SiO₂ → Si + CO

On balancing it : 2C + SiO₂ → Si + 2CO

⇒ 2 mole of carbon produces 2 mole of carbon monoxide

or 2×12=24 g of carbon produces 2×(12+16)=56 g of carbon monoxide

⇒ Expected yield of carbon monoxide when 32.5g of carbon is heated with silicon dioxide is 32.5× $\frac{56}{24}$

⇒ Expected yield = $\frac{455}{6}$ = 75.8 g

Actual yield is given as 28.8 g

⇒ The percent yield of carbon monoxide = $\frac{Actual\ yield}{Expected\ yield}$ ×100

= $\frac{28.8}{75.8}$ ×100

≅<u>38%</u>
