4)Calculate the mass of aluminum metal required to release2160mL of hydrogen gas at STP from sulfuric acid given theUNBALANCED equation: (Answer = 1.73g Al) Al(s) + H2SO4(aq)------------- Al2(SO4)3 + H2(g)
Given the UNBALANCED equation, HCl(g) + O2(g) ---------- Cl2(g)+ H2O(g)
5) Calculate the volume of HCl gas to yield 50.00ml of chlorinegas (Answer = 100.0mL)
6) Calculate the volume of O2 gas to yield 50.00mL of Cl2 gas(Answer=25.00mL)
7)In a reaction, 75.0g of manganese(IV)oxide react with 30.0g ofaluminum. Identify the limiting reactant and calculate the mass ofaluminum oxide produced (Answer: Al, 56.7g) 3MnO2(l) + 4Al(l)------------- 3Mn(l) + 2Al2O3(s)
8)If 10.0L of C2H6 reacts with 25.0L of O2, what is the limitingreactant, and what is the volume of CO2 produced? (Answer = O2,14.3L of CO2) 2C2H6(g) + 7O2(g) ---------------- 4CO2(g) + 6H2O(g)Given the equation: NH3(g) + HNO3(aq) ----------- NH4NO3(s)
9) If 15.0kg of NH3 is used, what is the theoretical yield ofNH4NO3? (Answer = 70.5kg)
10) If 65.3kg of NH4NH3 is recovered, what is the percent yield?(Answer=92.6%)
