In order to determine if compounds X and Y are the same, the mole percentages of the elements present should be equal in both compounds.
For compound X
number of moles H = 15/ 1 =15 mol H
number of moles O = 120/ 16 = 7.5 mol O
total moles = 22.5 mol
mole percentages
% mole H = 67%
% mole O = 33%
For compound Y
mole of H = 2 /1 = 2
mole of O = 32/16 = 2
total mole = 4 mole
mol %
% mol H = 50%
% mol O = 50%
there the two compounds are not the same.
A calcium bromide for this right on a quiz
The answer would be A. Evaporation. Heat of fusion in any types of matter is the amount of heat transfer to a matter that allows it to change its form by gathering or absorbing an amount of heat that could change is form either its from solid to liquid, liquid to gas or vice versa.
Synthesis, this is a synthesis reaction because it went from A+X=AX
