A sample of carbon dioxide occupies a volume of 2.54L at 175.6 kPa pressure. What pressure would the gas exert if the volume was decreased to 1.75 L?

The answer to your question is  P2 = 254.9 kPa

Explanation:

Data

Volume 1 = V1 = 2.54 l

Pressure 1 = P1 = 175.6 kPa

Volume 2 = V2 = 1.75 l

Pressure 2 = P2 = ?

Process

To solve this problem use Boyle's law.

          P1V1 = P2V2

-Solve for P2

         P2 = P1V1 / V2

-Substitution

         P2 = (175.6 x 2.54) / 1.75

-Simplification

         P2 = 446.02 / 1.75

-Result

         P2 = 254.9 kPa

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
