Calculate the theoretical values of g metal / moles H2 for each of the reactions shown below. To do this, you will look up the molar mass for each metal, and divide by the moles of H2 shown in the balanced equation. (Note: fractions may be used to balance the equation to keep the moles of metal at 1) g La / moles Hz (LaCl, is produced) La (s) + 3 HCI (aq) — 32 H, (g) + LaCl, (aq)​
