Mastering Chemistry: Hwa32-Midterm 3 Topic Review Google Chrome https:// Schafer Fall 2016 Chem 151 HAM32 Misterm RT2Ric Mass-to-Mass Conversions in Stoichiometry t Mass-to-Mass Conversions in Stoichiometry The coeficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. The molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH (g) +O2 (g 0- CO2 (g) +H20(g) This type of reaction is referred to as a complete combustion reaction. Part A What coefficients are needed to balance the equation for the complete combustion of methane?Enter the coefficients in the order CH4, O2, CO2 and H2O, respectively.
