Answer:
The water will continue to heat up as the experiment progresses.
Explanation:
When a person's fingers are cold or has a muscles ache, one can use chemical hand warmers to heat them up. There are two types of chemical hand warmer products, and they all depend on exothermic chemical reactions to work.
However, ammonium chloride dissolution is endothermic but its crystalization is exothermic. When used as a hand warner with a calorimeter, it is found that the temperature of the water increases steadily due to the crystalization of the ammonium chloride. Hence the answer.
In a combustion reaction, one of the reactants is always oxygen.

Answer:
Mendeleev left gaps in his periodic table because he knew that these elements existed, but had not yet been discovered. He believed that the elements would be eventually found and would fit perfectly into the gaps. Two such elements are Germanium and Gallium.
