Exhibit 8-1

Question

For the following questions, consider the equation below. Zinc will react with a solution of hydrochloric acid to produce hydrogen gas:

Zn(s) + 2 HCl(aq) ® ZnCl2(s) + H2(g)

Refer to Exhibit 8-1. How many moles of hydrochloric acid react with one mole of zinc?

1. the same number as the number of moles of hydrogen produced

2. between 1 and 2 depending on how much hydrogen gas is formed

3. 1

4. 2

I am working on some practice questions in the book, but there is not an answer to this question. Does anyone know the answer?

Thanks
