A sample of krypton occupies 15.0 L at a pressure of 2.1 atm. Use Boyle's Law to find the pressure of the krypton when the volume is decreased to 4L.

7.5 atm

Explanation:

Given that,

Initial volume, V₁ =  15 L

Pressure, P₁ = 2.1 atm

Final volume, V₂ = 4L

We need to find the final pressure. The mathematical relation between volume and pressure is given by :

So, the final pressure is equal to 7.5 atm.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
