C6H10O5(s) + 602(g) → 6CO2(g) + 5H2O(g) + heat
8. Show a numerical setup for calculating the percent composition by mass of carbon in C&H10O, (gram 6
mass = 162.14 g/mol).
9. Calculate the mass of CO2 (gram-formula mass = 44.01 g/mol) produced when 0.64 kg of cellulose is completely
combusted to the nearest hundredth.
10. Draw Lewis-electron dot diagram of compound CO2 and determine the molecular polarity by drawing the
polarity vectors.
