Answer to Question #138726 in General Chemistry for jayla

Question

How many grams of carbon dioxide would be formed if 38.9 g C2H2 reacted completely with oxygen?

Answer 1

Given 38.9g of C2H2 completely reacted with O₂

_{equation: 2C2H2 + 5O2 = 4CO2 + 2H2O}

_{moles of C2H2 = 38.9/26.0 = 1.496}

_{mole ratio of C2H2 to CO2 = 2:4}

_{moles of CO2 = 4*1.496/2 = 2.992 moles}

_{mass of CO2 produced = 2.992 moles * 44 g/mol= 131.662g}
