A)3 6 6 3 4
B)8 6 5 10 5
C)5 10 10 5 5
D)1 2 2 1 1
E)none of these

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between sodium carbonate and hydrochloric acid is:

Na2CO3 + 2HCl → 2NaCl + CO2 + H2O

This equation shows that one mole of sodium carbonate reacts with two moles of hydrochloric acid to produce two moles of sodium chloride, one mole of carbon dioxide, and one mole of water. Therefore, the correct set of coefficients for the balanced reaction is 1, 2, 2, 1, 1, which is option D.
