The pressure in a container at 30 degrees celsius was 2.3 atm and had a volume of 2.2l, whatwould the volume be if the conditions were changed to stp

For a fixed mass of gas we can use the combined gas law.

(P1V1)/T1 = (P2V2)/T2

where P1 is pressure , T1 is temperature and V1 is volume at the first instance

and P2 is standard pressure and T2 is standard temperature and V2 is the volume at STP conditions

temperatures at both instances should be in kelvin scale

T1  - 30 °C + 273.15 = 303.15 K

T2 - 273.15 K

substituting the values in the equation

(2.3 atm x 2.2 L) / 303.15 K = (1.0 atm x V2) / 273.15 K

V2 = 4.6 L

the volume at STP is 4.6 L

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
