Answer #1

Ca + 2H2O ------------> Ca(OH)2 + H2

2Na + 2H2O ------------> 2NaOH + H2

2K + 2H2O ------------> 2KOH + H2

2Li + 2H2O ------------> 2LiOH + H2

Mg + 2H2O ------------> Mg(OH)2 + H2 (require steam instead of water)

2Al + 6H2O ------------> 2Al(OH)3 + 3H2 (require steam instead of water)

S + H2O-----------------> No Reaction

All the first group members of periodic table (Li, Na, K, Rb, Cs, Fr) reacts vigoursly with water to give hydrogen. As we go across in the periodic table (along a period) the reactivity decreases and hence we require harsher condition in the form of high temperture. The non metals like sulfur do not react with water
