used to power some motor vehicles. THE combustion of propane is shown in the equation below. C3H8 + 5 O2 3 CO2 + 4 H20 → The combustion of 100 g of propane produces 299.4 g of carbon dioxide. Assume the combustion of propane produces the same amount of energy per gram as the combustion of octane. c. Based on this information and your calculations, identify which fuel, octane or propane, is less harmful to the environment. Justify your answer. _______________________________________________________________________________________________ Worksheet: Writing and Identifying Equations CHEMISTRY: A Study of Matter Directions: a) Write balanced equations for the following word equations. b) In the blank to the left of the equation, tell if the equation is synthesis (S), decomposition (D), combustion (C), single replacement (SR), or double replacement (DR). _____ potassium chloride + silver (I)nitrate yields potassium nitrate + silver (I) chloride _____ iron metal + copper (II) sulfate yields iron (II) sulfate + copper metal
