What happens when calcium is treated with water?
i) It does not react with water.
ii) It reacts violently with water.
iii) It reacts less violently with water.
iv) Bubbles of hydrogen gas formed stick to the surface of calcium.
When calcium is treated with water, it reacts less violently with water to form milky Calcium Hydroxide and Hydrogen gas, along with release of heat. The hydrogen gas stick to the surface of the metal, causing the metal to float.
Hence, when Calcium reacts with Water, the products are Calcium Hydroxide and Hydrogen gas.
