Mg + 2HCl --> MgCl2 + H2(g)
Assuming STP, how many moles of hydrogen gas did Carl and his partner collect if they collected 5.6L?
Curious Carl and his lab partner were conducting a variety of experiments to produce gases: hydrogen, oxygen, and carbon dioxide. In one experiment, they added a piece of magnesium ribbon to 10 milliliters of hydrochloric acid. They observed bubbles being produced and did a variety of tests to identify the escaping gas; it proved to be hydrogen. The reaction is represented by the following equation.
A) 0.250 moles
B) 2.78 moles
C) 5.60 moles
D) 11.2 moles
