The substances containing only C, and H, or C, H and one or more
other elements are given. Combine the following reactions with
molecular Oxygen O2 as one reaction, and then Ozone O3 as a second
reaction for the same substance This means you will write 12
complete reactions for each combustion type, providing both the
products and the reactants. For each substance containing a hetero
atom (N, S, P), assume it forms NO2, SO2, or P2O3.
1. Heptane C7H16 2. Benzoic Acid C7H6O2 3. Diethyl Ether C4H10O 4.
Diethyl Sulfide C4H10S 5. Triethyl Amine C6H15N 6. Trimethyl
Phosphine C3H9P
Here are two examples that are not balanced, since the reactant has
an unknown formula. Assume the substance is the limiting reactant.

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...
