The theoretical number of moles of water produced from 8 moles NaHCO₃ is ________.

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between NaHCO3 and H2SO4 is:

2 NaHCO3 + H2SO4 → Na2SO4 + 2 H2O + 2 CO2

From the equation, it is clear that for every 2 moles of NaHCO3 we need 1 mole of H2SO4 to produce 2 moles of water. Therefore, for 8 moles of NaHCO3 we need 4 moles of H2SO4 to produce 8 moles of water. Therefore, the theoretical number of moles of water produced is 8. Answer B (4) is incorrect, therefore answer C (8) is the correct choice.
