1. 2al + 3h2so4 -> al2(so4)3 + 3h2 in the balanced equation above, what is the ratio of the reactant aluminum to the product aluminum sulfate?

2. what coefficients would be needed to balance the following chemical equation? put them in order separated by commas. if no coefficient is needed, put a 1. example: 1,2,3,4 c2h4(g) + o2(g) > co2(g) + h2o(g) a. 1,2,3,3 b. 2,1,1,2 c. 1,3,2,3 d. 1,3,2,2

3. 25 grams of mg react with 20 grams of hcl. identify the limiting reagent. how much of the excess reagent remains (in grams)
mg(s) + 2hci(aq) > mgci2(aq) + h2(g)
