Question
Which one statement in italics is NOT correct? Other given information is correct.
a.
The condensation of steam of liquid water is exothermic.
b.
When 1 mole of NH4NO3 dissolves in water, the temperature of the water decreases. This dissolution process is endothermic.
c.
The enthalpy change for freezing 1 mol of wter is -6.0 kJ. This process is exothermic.
d.
1 mol of Ca + 1 mol Br2 has a higher enthalpy than 1 mole CaBr2. Thus, the combination reaction of calcium with bromine to give calcium bromide is exothermic.
e.
When sodium bicarbonate decomposes, heat is absorbed from the surroundings. Thus, the decomposition of sodium bicarbonate is exothermic.
