A:
Preview: ... mass of N2 is 28 g/mole. So 45 g of N2 is 45/28 mole. Based on the reaction equation, you need 6 moles of NO to produce 5 moles of N2. So 45/28 mole of N2 will need (6/5)*(45/28) mole of NO or 1.93 mole. The molar mass of NO is 30 g/mole. So 1.9286 mol of NO equals to 1.9286*30=57.858 g of NO.       in the reaction of N2 with H2 to form NH3, how many moles of H2 are needed to react with 1.22 moles of N2? ANSWER: The balanced equation is N2 + 3H2 --> 2NH3 Based on this equation, 3 moles of H2 are needed to react with 1 mol of N2. So 1.22 moles of N2 will need 1.22*3 = 3.66 moles of H2.       how many moles of water are produced from the reaction of 0.12 moles of oxygen according to the following equation? 2 H2 + O2 ----> 2 H20 ANSWER: Based on the balanced equation, 1 mole of oxygen produces 2 moles of water.   So 0.12 moles of O2 will produce 0.12*2 = 0.24 moles of H2O.     if 16.0 g of CH4 is reacted with 32.0 g of O2 according to the following unbalanced equation, what is the limiting reagent? CH4 + O2 ---> CO2 + H20 ANSWER: The balanced equation is CH4 + 2 O2 ---> CO2 + 2 H20 The molar mass of CH4 is 16 g/mole. So 16 g of C ...
