Question 27

Barium and strontium are in Group 2 of the periodic table, below calcium.

Barium reacts with water to form barium hydroxide, Ba(OH)2\text{Ba(OH)}_2Ba(OH)2​, and hydrogen gas, H2\text{H}_2H2​.

Ba(s)+2H2O(l)→Ba(OH)2(aq)+H2(g) \text{Ba(s)} + 2\text{H}_2\text{O(l)} \rightarrow \text{Ba(OH)}_2\text{(aq)} + \text{H}_2\text{(g)} Ba(s)+2H2​O(l)→Ba(OH)2​(aq)+H2​(g)

Describe two observations that would be made when a small piece of barium is added to a beaker of water.
