I have got five questions on my study guide that I am unsure about. I am really liking the format of how you have been working through the other problems. It has really helped me understand things.
2H2(g) + O2(g) → 2H2O(g)
2. Iron reacts with hydrochloric acid to produce iron(II) chloride and hydrogen gas.
Fe(s) + 2 HCl(aq) → FeCl2(aq) + H2(g)
What mass of H2(g) is produced from the reaction of 5.2 g Fe(s) with excess hydrochloric acid?
3. What mass of oxygen will react with 2.64 g of magnesium?
2Mg(s) + O2(g) → MgO(s)
4. A mass of 4.00 g of H2(g) reacts with 2.00 g of O2(g). If 1.94 g of H2O(l) is collected, what is the percent yield of the reaction?
2H2(g) + O2(g) → 2H2O(l)
5. What are the values for x and y, respectively, in CaxHyPO4?
