Question 119

The balanced equation for this reaction is:

Ca+2HCl→CaCl2+H2 \text{Ca} + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2 Ca+2HCl→CaCl2​+H2​

In another experiment, 0.08 moles of hydrochloric acid, HCl\text{HCl}HCl, were reacted with 0.2 g of calcium turnings.

Calculate the number of moles of calcium, Ca\text{Ca}Ca, in the 0.2 g sample of calcium turnings. (relative atomic mass: Ca=40\text{Ca} = 40Ca=40)
