Question 1

Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.91 mol of magnesium and 3.91 mol of hydrochloric acid are reacted, how many grams of magnesium chloride are produced?

Accepted Answer

The answer of Consider the reaction of magnesium metal with...

Question 2

Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.85 mol of magnesium and 3.85 mol of hydrochloric acid are reacted, how many moles of excess reactant are left over?

Accepted Answer

The balanced chemical equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is: Mg + 2HCl → MgCl2 + H2. This shows that 1 mole of Mg reacts with 2 moles of HCl. Since both Mg and HCl are provided in equal moles (3.85 mol), HCl is the limiting reactant because it would be completely used up first, reacting with only half as much Mg (1.925 mol of Mg), leaving 1.93 mol of Mg unreacted.

Question 3

Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.01 mol of magnesium and 3.01 mol of hydrochloric acid are reacted, how many moles of magnesium chloride are produced?

Accepted Answer

The balanced chemical equation is Mg + 2HCl → MgCl2 + H2. Since 2 moles of HCl are needed for every mole of Mg, HCl is the limiting reactant. With 3.01 mol of HCl, only 1.505 mol of MgCl2 can be produced.

Question 4

Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. If 3.00 mol of magnesium and 3.00 mol of hydrochloric acid are reacted, how many grams of excess reactant are left over?

Accepted Answer

The answer of Consider the reaction of magnesium metal with...
