A piece of radioactive radium is added to water.

Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction.

Ra (s) + H₂O (g) → Ra (OH) ₂ (aq) + H₂ (g)

Explanation:

Radioactive radium reacts easily with water produces radium hydroxide and hydrogen gas. In this reaction, Radium is sin solid state reacts with the water in the gaseous state to produces aqueous radium hydroxide and the hydrogen gas. This reaction occurs rapidly than in Barium. We can write this reaction as,

Radium (s) + water (g) → Radium hydroxide (aq) + Hydrogen (gas)

This can be represented using the symbols as,

Ra (s) + H₂O (g) → Ra (OH) ₂ (aq) + H₂ (g)

Thus the above process can be expressed with such chemical reaction.
