Sample Question
Two chemists are designing instant hot and cold packs for a sports medicine supply company. Their design uses chemicals that react with water to either heat up or cool down the water inside the packs. They are investigating the reaction of ammonium chloride with water to determine whether it is exothermic or endothermic. Chemist A read a study done recently by the National Institute for Standards and Testing, which reported that 27.6 kilojoules of energy are absorbed by 100 grams of ammonium chloride when it is mixed with water. Chemist B measured the temperature of the water in which the reaction takes place before and after the reaction. The results are displayed in the table. Question: Does Chemist B's results support or contradict the evidence reported by Chemist A? You may use the calculator

Chemist B's results supports Chemist A's data because the reaction gains less energy than the water does.

Chemist B's results contradicts Chemist A's data because it indicates that the reaction gains energy instead of losing it.
