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...

Question #7: After lithium hydroxide is produced aboard the space shuttle by reaction of Li2OLi2O with H2OH2O (Li2O(s)+H2O(g)→2LiOH(s))(Li2O(s)+H2O(g)→2LiOH(s)), it is used to remove exhaled carbon dioxide from the air supply according to the equation LiOH(s)+CO2(g)→LiHCO3(s) A) How many grams of CO2CO2 can 410.0 gg of LiOHLiOH absorb? Question #8: An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOzCxHyOz). Combustion of 7.00 gg of this compound produced 10.3 gg of carbon dioxide and 4.20 gg of water. A) How many...

please help me calculate.
Note: The mass of carbon dioxide gas produced during the reaction can be determined by how m mass was lost from the chemical reaction. Think about it for a moment; those bubbles that were forming carbon dioxide gas molecules escaping from the beaker, while all the other chemicals remained behind. You must first compute the combined mass of vinegar and baking soda you started with, and from this subtract the mass of your solution after the...
