Question

Metallic magnesium reacts with steam to produce magnesium hydroxide and hydrogen gas. a. If 16.2 g Mg are heated with 12.0 g H2O, what is the limiting reactant? b. How many moles of the excess reactant are left? c. How many grams of each product are formed?

Answer 1

Answer:

0.334 mol

Explanation:

What is the limiting reactant when 16.2 g Mg is heated with 12.0 g H2O? Magnesium hydroxide and hydrogen gas are produced when metallic magnesium interacts with steam. How many moles of surplus reactant remain after 16.2 g Mg is heated with 12.0 g H2O? There is still 0.334 mol of surplus reactant.
