A gas has its pressure decrease from 760 torr to 320 torr at 225k. Was is the initial temperature of the gas?

Explanation:

Given the following data;

Final pressure, P2 = 760 Torr

Initial pressure, P1 = 320 Torr

Final temperature, T2 = 225K

To find the initial temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

Making T1 as the subject formula, we have;

Substituting into the equation, we have;

Therefore, the initial temperature of the gas is 94.75 Kelvin.

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.

fe 55.85 g/mol and h2o 18.02 g/mol.
