N2 (g) + 3 H2 (g) --> 2NH3 (g) In a certain reaction, 5.0 moles of hydrogen is reacted with excess nitrogen. To determine how many moles of ammonia (NH3) are produced based on the 5 mols of hydrogen, what conversion factor(s) should be used? (choose all that apply) {Ans: - [2 mol NH3 / 3 mol H2] - [3 mol H2 / 2 mol NH3]}Name the following hydrate FeSO4 · 9 H2O. {Ans: iron (II) sulfate nonahydrate}How many molecules are in 3.9 moles of water? {Ans: 2.3 x 1024 molecules of water}Ga2O3(s) + 3SOCl2(l) --> 2GaCl3(s) +3SO2(g) In a certain reaction, 35.9 g of Ga2O3 is reacted with 55.4 g SOCl2.The GaCl3 produced is collected and its mass founded to be 48.83 g. What is the limiting reactant? {Ans: SOCl2}In a chemical reaction, one reactant, called the ______ reactant, will control the extent of the reaction. A portion of the other reactants, called the ________ reactants, will remain. {Ans: limiting; excess}If the empirical formula of a compound is known, what is needed in order to determine the molecular formula? {Ans: The molar mass}N2 (g) + 3H2 (g) -->2 NH3 (g) The equation above
