Answer:
Required Answer:-
We know that metals react with water to release Hydrogen gas (H2). Sodium and Calcium, both are metals. Hence, Hydrogen is released in both cases. Now let's see, Why the above phenomenon occurs??
Case 1: Sodium + Water
Sodium is a very reactive metal. It reacts with water vigorously because water is the reagent here. As a result, Hydrogen gas is released. The reaction is highly exothermic and violent, hence releases a lot of heat. This causes the hydrogen to burn and catch fire because hydrogen is a combustible gas.
Case 2: Calcium + Water
Calcium is little less reactive as compared to Sodium. The reaction of calcium and water is little less violent and hence the heat is released is not sufficient enough to burn the hydrogen released. Hence, when calcium metal is added to water the gas evolved dose not catch fire.
