59. Consider the following balanced chemical equation: 3A +2B2C + 4D If you have 5.8 moles of A, how many moles of D can be formed? 60. A hydrocarbon is found to be 92.3% carbon. What is the empirical formula for this compound? 61. Using the following chemical equation for the burning of methane, answer the question that follows: CH(g) + 2O2(g) - CO2(g) + 2H2O(1) If 128.0g of CH4 is mixed with excess O2 and the mixture is ignited,...

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...
