Question
Jeremy writes the following symbol equation for the reaction in the previous question:K (s) + H2O (l) KOH (aq) + H2 (g)Determine why this equation is unbalanced.There are 2 hydrogens on the reactant side and 1 oxygen on the product sideThere are 2 hydrogens on the reactant side and 3 hydrogens on the product sideThere are 2 hydrogens on the reactant side and only 1 hydrogen on the product sideThere is K on the reactant side and KOH on the product side
Solution
The equation is unbalanced because there are 2 hydrogens on the reactant side (H2O) and 3 hydrogens on the product side (KOH and H2). In a balanced chemical equation, the number of each type of atom must be the same on both the reactant and product sides.
