Consider the following elements: calcium, rubidium, strontium, and lithium. Which will react most violently with water? Write the balanced reaction equation that occurs.
Calcium; Ca(s) + 2 H2O(l) → Ca2+(aq) + 2 OH–(aq) + H2(g)
Rubidium; 2 Rb(s) + 2 H2O(l) → 2 Rb+(aq) + 2 OH–(aq) + H2(g)
Strontium; Ca(s) + 2 H2O(l) → Sr2+(aq) + 2 OH–(aq) + H2(g)
Lithium; 2 Li(s) + 2 H2O(l) → 2 Li+(aq) + 2 OH–(aq) + H2(g)
