Using the equation below, what is the correct form of the conversion factor needed to convert the number of moles of h2o to the number of moles of nh3 produced?

mg3n2 + 6h2o --> 3mg(oh)2 + 2nh3

2 mol nh3
6 mol h2o

18 g h2o
17 g nh3

1 mol mg3n3
6 mol h2o

18 g h2o
1 mol h2o

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
