What is the partial pressure of water vapor in an air sample when the total pressure is 1.00 atm, the partial pressure of nitrog

Inga [223]

Answer:

0.0156 atm

Explanation:

Let the partial pressure of water vapor be $P_w$ .

Given:

Total pressure of air sample is, $P_T=1.00\ atm$

Partial pressure of nitrogen is, $P_n=0.79\ atm$

Partial pressure of oxygen is, $P_o=0.19\ atm$

Partial pressure of all other gases is, $P_{other}=0.0044\ atm$

From Dalton's law of partial pressure, we know that, the total pressure of a mixture of gases is equal to sum of partial pressure of each individual gas.

So, total pressure of air sample is equal to the sum of partial pressure of nitrogen, oxygen, other gases and water vapor.

Therefore, framing in equation form, we have:

$P_n+P_o+P_{other}+P_w=P_T$

Plug in the given values and solve for $P_w$ . This gives,

$0.79+0.19+0.0044+P_w=1.00\\\\0.9844+P_w=1.00\\\\P_w=1.00-0.9844\\\\P_w=0.0156\ atm$

Therefore, the partial pressure of water vapor in an air sample is 0.0156 atm.

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?

RSB [31]

Answer: A) NO increases the rate at which $SO_3$ molecules are formed.

Explanation:

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.

$2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)$

Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among $SO_2$ and $O_2$ molecules will incraese which in turn will lead to formatioon of more $SO_3$ molecules.

Components of crude oil can be separated through a process called _____.

Drupady [299]

Answer:

Components of crude oil can be separated through a process called <u><em>fractional distillation</em></u>.

Explanation:

Fractional distillation can be described as a method of distillation in which a liquid mixture is separated based on the different boiling points of the components present in the mixture. The components of crude oil have different boiling temperatures hence, they can be separated by the process of fractional distillation.

The fractionating column has high temperatures at the bottom so components with high temperatures are separated at the bottom. The upper columns have lower temperatures. Components with lower boiling temperatures get separated at the upper columns.
