*Make proportions to solve. Find the rate from the question 1.

Question 1 is 40.

There are 400 grams of NaCI. There are 10 drops.

Divide 400 by 10.

400 / 10 = 40

40 is the answer.

Now all we do is repeat the same process for question 2.

Question 2 is 20.

There are 800 grams of barium peroxide, and there are 40 drops.

Divide 800 by 40.

800 / 40 = 20

Answer = 20.

Answer:

1. 40 grams of NaCI

2. 20 grams of Barium Peroxide

Explanation:

<h3><u>In this question, we have to divide to find the amount of each element in a drop. </u></h3>

For Question 1, there are 400 grams of NaCI. There are 10 drops.

So, we have to divide 400 by 10.

  • 400 / 10 = 40

We get 40 as our result, so 40 is the answer.

<h3><u>Same for this question, we use the process we did before.</u></h3>

There are 800 grams of barium peroxide, and there are 40 drops.

So, we divide 800 by 40.

  • 800 / 40 = 20

We have the answer as 20.

Our final answers are going to be listed below:

  • Question 1 - 40
  • Question 2 - 20

Hope this helps you!

The reaction
Aliun [14]

From he calculations, we can see that the total pressure at equilibrium is 21 atm.

<h3>What is  equilibrium constant?</h3>

The term equilibrium constant commonly describes the constant that that shows the extent of conversion of reactants to products.

We have to find the pressure of each gas as follows;

For H2

P = nRT/V = 4.553 /2  × 0.082 × 1000/8.89 L = 21 atm

Using the ICE table;

         C(s)   +   2H2(g)  ⇌  CH4(g)

I                       21 atm          0

C                      -x                  +x

E                     21 - x              x

0.263= x/(21 - x )^2

0.263(21 - x )^2 = x

38 - 11x - 0.263x^2 = x

0.263x^2 + 12x - 38 = 0

x=2.97 atm

At equilibrium, we have;

(21 - 2.97) + 2.97 = 21 atm

Give an example of a non-biological chemical reaction that involves carbon. Name the process that converts a solid compound into
xxMikexx [17]

Answer:

The process that converts a solid mcompound into a gas is sublimation.

E.g- dry ice, solid iodine and ammonium salts

when the above solid are heated, only particles which are found on the surface of the solid gain enough energy and break all forces of attraction and form a gas.
