Possibly decomposition but not sure
I think it might be a decomposition.
Reasons why percent yield is more than 100
Typically, percent yields are understandably less than 100% because of the reasons indicated earlier. However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.
figure it out
Boiling Point is a physical property because It is the the only one that doesn’t require a chemical reaction
