Mg3n2(s)+6h2o(l)→3mg(oh)2(s)+2nh3(g ) when 36.0 g of h2o react, how many grams of nh3 are produced? when 36.0 g of h2o react, how many grams of nh3 are produced? 34.0 g 10.0 g 5.67 g 11.3 g 102 g

11.3 g of are produced from 36.0 g of

Explanation:

1. The balanced chemical equation is the following:

2. Use the molar mass of the , the molar mass of the and the stoichiometry of the balanced chemical reaction to find how many grams of are produced:

Molar mass = 18

Molar mass = 17

Therefore 11.3 g of are produced from 36.0 g of

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
