Let’s compose the reaction equation: Ca + H2O = Ca (OH) 2 + H2
Let’s arrange the coefficients in the equation: Ca + 2H2O = Ca (OH) 2 + H2
Let’s calculate the sum of the coefficients in the equation: before H2O, the coefficient is 2, before the rest of the compounds, the coefficient is 1.
1 + 2 + 1 + 1 = 5.
Answer: the sum of the coefficients in the reaction of calcium and water is 5
