X Incorrect. Is the equation properly balanced? Did you use the correct mole ratio? How many moles of MnCl2 will be produced when 2.70 mol of H2O are formed? mol MnCl2 the tolerance is +/-2% xIncorrect. Did you use the correct mole ratio? Did you use the mass of Cl or Cl2? How many grams of Cl2 will be produced when 4.29 mol Mn02 react with excess HCI? grams Cl2 the tolerance is +/-2% Incorrect. Did you remember to convert from kg to g? How many moles of HCI are required to produce 1.18 kg of MnC12? mol HCI the tolerance is +/-2%Explanation / Answer
MnO2(s) + 4HCl(aq) ----< MnCl2(s) + 2H2O(l) + Cl2(g)
1 mol MnO2(s) = 4 mol HCl(aq) = 1 mol MnCl2(s) = 2 mol H2O(l) = 1 mol Cl2(g)
1) no of mol of MnCL2 produced = 2.7*1/2 = 1.35 mol
2)
no of mol of MnO2 REACTED = 4.29 MOL
no of mol of cL2 formed = 4.29 mol
MASS of Cl2 = 4.29*71 = 304.6 g
3)
no of mol of MnCL2 produced = 1.18*10^3/125.85 = 9.38 mol
no of mol of HCl required = 9.38*4/1 = 37.52 mol
