Question

Consider the following elements: calcium, rubidium, strontium, and lithium. Which will react most violently with water? Write the balanced reaction equation that occurs.

Accepted Answer

Rubidium; 2 Rb(s) + 2 $$H_{2}O(l$$) → 2 $$Rb^{+}(aq) + 2$$ $$OH^{–}(aq) + H$$_{2}(g)

Answer

Calcium; Ca(s) + 2 $$H_{2}O(l$$) → $$Ca^{2+}(aq) + 2$$ $$OH^{–}(aq) + H$$_{2}(g)

Answer

Strontium; Ca(s) + 2 $$H_{2}O(l$$) → $$Sr^{2+}(aq) + 2$$ $$OH^{–}(aq) + H$$_{2}(g)

Answer

Lithium; 2 Li(s) + 2 $$H_{2}O(l$$) → 2 $$Li^{+}(aq) + 2$$ $$OH^{–}(aq) + H$$_{2}(g)
