Given the balanced equation representing a reaction:
al2(so4)3 +6naoh ==> 2al(oh)3 + 3na2so4
the mole ratio of naoh to al(oh)3 is
(1) 1: 1 (2) 3: 1
(3) 1: 3 (4) 3: 7

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
