Aqueous hydrochloric acid (HCl) will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride (NaCl) and liquid water (H2O). Suppose 2.9 g of hydrochloric acid is mixed with 6.11 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 2 significant digits.

For each reaction in the table below, write the chemical formulae of any reactants that will be oxidized in the second column of the table. Write the chemical formulae of any reactants that will be reduced in the third column.
