Consider the decomposition of aluminum sulfide into aluminum metal and solid S₈ (one of the forms of sulfur). You've determined the compound formed between aluminum and sulfur will be Al₂S₃. This compound decomposes to form solid aluminum and sulfur (as S₈). Write the balanced chemical equation for the reaction.

According to the following reaction, how many grams of mercury will be formed upon the complete reaction of 31.3 grams of mercury(II) oxide? 2HgO(s) → 2Hg(l) + O₂(g) ||| g mercury

suppose a student reacts 1.57 g Ca with O2 gas. In his/her calculations however S/he mistakenly calculate the theoretical yield with 1.97 g Ca. Will the theoretical yield of CaO be  too high, too low, or unaffected?
