Caesium reacts extremely vigorously with water to form caesium hydroxide and hydrogen gas.
2Cs(s)+2H2O(l)→2CsOH(aq)+H2(g) 2\text{Cs(s)} + 2\text{H}_2\text{O(l)} \rightarrow 2\text{CsOH(aq)} + \text{H}_2\text{(g)} 2Cs(s)+2H2O(l)→2CsOH(aq)+H2(g)Predict three observations you would make when a small piece of caesium is added to a large volume of water.
