Which of these equations are correct? Select all that apply

nikitadnepr [17]

Answer:

The answer to your question is below

Explanation:

There are 4 laws of gases

- Charles

$\frac{V1}{T1} = \frac{V2}{T2}$

- Gay Lussac

$\frac{P1}{T1} = \frac{P2}{T2}$

- Boyle - Mariotte

P1V1 = P2V2

- General law of gases

$\frac{P1V1}{T1} = \frac{P2V2}{T2}$

Let's use these formulas to answer the question

p2 = V2/P1 This is not a law of gases

p1= V1/k This formula is similar to Boyle mariotte equation

but is not.

V2 = k/P2 This equation is correct is Boyle Mariotte formula

V2 = P1V1/ P2 This equation is also correct is Boyle Mariotte formula

V1 = P1/P2 (V2) This equation is incorrect

P2 = (P1) V1/V2 This equation is correct is Boyle mariotte formula

The reactants in a chemical reaction contain 900 J of chemical energy. The products of the reaction contain 9000 J of chemical e

natta225 [31]

For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
