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...

Write the state of matter for every substance in the chemical reaction. Explain your limiting reactant determinations. Mark every measured number showing the significant figures (SF). Do not round any intermediate values. (you can show two digits past the marked SF) Show subtraction and addition in the vertical format. Show your final answer before rounding and then in the final form, rounded correctly. Every number must have units and substances. You can use tables or other means to increase your...
