            b. What type of reaction is this? _________________________________

c. How many grams of H2O are made from 45.6 g of O2?

d. How many liters of CO2 are produced from 389.44 L of O2?

e. How many grams of C6H14 are needed to make 87.10 mol of CO2?

f. How many moles of H2O are there if you start with 508.33 g of C6H14? 

Answer 1

2C₆H₁₄ + 19O₂ ==> 12CO₂ + 14H₂O ... balanced equation

b) Combustion reaction

c) 45.6 g O₂ x 1 mol O₂/32 g x 14 mol H₂O / 19 mol H₂O x 18 g H₂O/mol H₂O = 18.9 g H₂O

d) 389.44 L O₂ x 12 L CO₂ / 19 L O₂ = 245.96 L CO₂

e) 87.10 mol CO₂ x 2 mol C₆H₁₄ / 12 mol CO₂ x 86 g C₆H₁₄/mol = 1248 g C₆H₁₄

f) 508.33 g C₆H₁₄ x 1 mol C₆H₁₄ / 86 g x 14 mol H₂O / 2 mol C₆H₁₄ = 41.38 moles H₂O
