Reaction: 3Ca(NO3)2 + 2Li3PO4 ⟶ 6LiNO3 + Ca3(PO4)2 A. Ca3(PO4)2 B. Ca(NO3)2 C. Li3PO4 D. LiNO3 - ....ANSWER...B 2 | P a g e How many moles of water are needed to react with 2.2 moles of Li2O? Given: Li2O + H2O ⟶ 2 LiOH A. None of the above B. 1.1 C. 4.4 D. 1.5 E. 2.2 - ....ANSWER...E How many moles of chlorine gas are needed to make 0.6 moles of sodium chloride? Given the reaction: 2 Na + Cl2 ⟶ 2NaCl A. 3.6 B. 0.3 C. 1.2 D. 0.6 E. Not enough info - ....ANSWER...B 3 | P a g e How many moles of NH3 can be produced by the reaction of 2.00 g of N2 with 3.00 g H2? Reaction: N2 (g) + 3 H2 (g) ⟶ 2 NH3 (g) A. 1.00 B. 0.235 C. 0.143 D. 0.0567 E. None of the above - ....ANSWER...C The reaction of one mole of nitrogen gas with three moles of hydrogen gas releases 92 kJ of thermal energy to the surroundings. Which of the following is TRUE? A. None of the above are true B. This reaction is exoth ermic C. This reaction has a negative enthalpy of reaction D. All of the above are true E. Complete reaction of two moles of nitrogen gas would release 184 kJ of thermal energy in this reaction. - ....ANSWER...D 4 | P a g e If the theoretical yield of a reactant is 1 44 grams and the actual yield of the reaction is 72 grams, the percent yield of the reaction is 200%. True False - ....ANSWER...False Given the following generic equation, 2A +3B ⟶ A2B3 Δ Hrxn = +444 kJ, if you completely reacted 1 mole of compound A, t he amount of heat absorbed would be 222 kJ. True False - ....ANSWER...True The limiting reactant is not necessarily the reactant with the least mass. True False - ....ANSWER...True Since heat must be supplied to melt ice, the melting of ice is an endothermic process and so has a positive enthalpy value.
