1Mg(s)+2HCl(aq)=1MgCl2(aq)+1H2(g)

 

if 2.5 mol of hydrochloric acid is reacted, how many moles of magnesium chloride is produced?

 

if 15.0g of magnesium is reacted (assume excess acid), how many grams of hydrogen gas will be produced?

 

how many grams of hydrochloric acid are needed to react all 15.0g Mg, or the minimum amount before it can be in excess for the reaction?
