Questions & Step-by-Step Solutions
How many moles of CO2 are produced from the complete combustion of 1 mole of C3H8?
Step 1: Write the chemical equation for the combustion of propane (C3H8).
Step 2: The balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O.
Step 3: Look at the coefficients in front of CO2 in the balanced equation.
Step 4: The coefficient in front of CO2 is 3, which means 3 moles of CO2 are produced.
Step 5: Since we started with 1 mole of C3H8, it produces 3 moles of CO2.
Stoichiometry – The calculation of reactants and products in chemical reactions based on balanced equations.
Combustion Reactions – A type of chemical reaction where a substance combines with oxygen to produce heat and light, typically resulting in CO2 and H2O.
