Answer to Problem 64E
The completed and balanced chemical equation is shown below.
Explanation of Solution
The products of the reaction of an alkali metal with water are hydroxide of the metal and hydrogen gas. This reaction is a replacement reaction in which the hydrogen ion is replaced by the metal.
The complete reaction is shown below.
The number of hydrogen atoms on both sides is not balanced. Balance them by multiplying the
The number of atoms on both sides is now balanced but in a balanced chemical equation, there is never fraction stoichiometry. Therefore, the whole equation will be multiplied by two to balance properly.
The equation is now completed and balanced.
