Asample of gas occupies a volume of 445 ml at a temperature of 274 k. at what temperature will this sample of gas occupy a volume of 499 ml? show all of the work used to solve this problem.

The   temperature  that    the  sample  of    gas  occupy   a  volume    of  499ml  is  calculated  using  Charles  law  formula
that  is  V1/T1  = V2/T2
V1=  445 ml
T1=  274  k
V2 =  499 ml
T2=  ?

from equation  above  T2  =  T1V2/ V1
=  274 k  x 499 ml/445ml  =  307.25  k

Answer:

a. energy is absorbed in the reaction.

explanation:

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.

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom.
