1. Uranium is distributed in a form called yellow cake, which is made from uranium ore. In the second step of the reactions that form yellow cake from uranium ore, uranyl sulfate, UO2SO4, is converted to (NH4)2U2O7. 2UO2SO4 + 6NH3 + 3H2O → (NH4)2U2O7 + 2(NH4)2SO4 a. What is the maximum mass, in kilograms, of (NH4)2U2O7 that can be formed from the reaction of 100 kg of water and 100 kg of ammonia with 481 kg of UO2SO4? b. Explain why two of these substances are in excess and one is limiting.
2. Consider the neutralization reaction that takes place when hydrochloric acid reacts with solid nickel(II) carbonate.
a. Write a conversion factor that relates moles of HCl to moles of NiCO3 for this reaction.
b. What is the minimum volume of 6.0 M HCl necessary to react completely with 14.266 g of solid nickel(II) carbonate, NiCO3?
