I believe that the answer would be C. The thermal energy is transferred from warm to cold, so yes, the thermal energy is transferred from the soda can to the ice, and no energy is lost. It also says that this is an isolated system, so no energy can be lost, or gained anyways. Hope this helps!
<span>air = 70 % N2
exhaled air =70%N2 + some less O2 compared to only air
2H2O2=2H2O+O2
NaHCO3=2NaHCO3 → Na2CO3 + H2O + CO2 = No O2 gas from decomposition
ssoooo NaHCO3 <exhaled air <air <H2O2
