Consider the reaction below. If 8.75 g of CH4 reacts with 18.95 g of O2 and 6.85 g of H2O is collected, what is the percent yield of H2O? Show clear work. [Atomic masses: C = 12.01 g, H = 1.008 g, O = 16.00 g] CH4 + O2 _ CO2 + H2O (unbalanced).

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
