Questions
What happens when calcium reacts with water? Write the chemical equation of the reaction of calcium with water.
Write a balanced equation for the reaction of the following:
Calcium with water

Solution
When calcium reacts with water, it forms calcium hydroxide and hydrogen gas. Due to the formation of hydrogen bubbles that stick to the surface of calcium, it starts floating on water.
\[\ce{Ca_{(s)} + 2H2O_{(l)} -> Ca(OH)2_{(aq)} + H2_{(g)}}\]
Notes
Students should refer to the answer according to their questions.
