What is the limiting reaction in Zn + HCl?

3. The limiting reactant is the reactant that gives you the smaller amount of product. Therefore HCI is the limiting reactant in this problem. In this reaction 9.4 grams of ZnCl2 will form and there will be leftover zinc that did not react.

answersilicon (si); oxygen (o);

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.
