A mixture contains KClO3 and KCl. When the mixture is heated, only the KClO3 decomposes via the following reaction:       2KClO3 (s) → 3O2 (g) + 2KCl (s) In an experiment to determine the percent KClO3 in a KClO3/KCl mixture, the mixture was heated in a crucible several times in order to bring it to constant mass. The following experimental data was obtained. Before Heating       Mass empty crucible + lid = 20.61 g       Mass crucible + lid+ KClO3/KCl mixture = 26.11 g

A mixture of C2H2 and CH4 has a total mass of 164 g. When this mixture reacts completely with excess oxygen, the CO2 and H2O products have a combined mass of 746.6 g. What mass of CH4 was present in the initial mixture?

62. Antacid Fizz When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate (NaHCO3), also called sodium bicarbonate, and citric acid (H₂CH₂O₂). 3NaHCO3(aq) + H₂CH₂O,(aq) → 3CO₂(g) + 3H₂O(l) + Na, C₂H₂O₂(aq) How many moles of Na₂C,H,O, can be produced if one tablet containing 0.0119 mol of NaHCO is dissolved?

Dilution Problems, Chemistry, Molarity & Concentration Examples,... M O O CHEMICAL REACTIONS Reaction sequence stoichiometry In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe₂O3(s) + 3CO(g) → 2Fe(s) + 3 CO₂ (g) E crosoft O V Blast furnaces extra pure iron from the iron (III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s) + O₂(g) 2 CO (g) W Suppose the yield of the first step is 84.% and the yield of the second step is 63.%. Calculate the mass of oxygen required to make 3.0 kg of iron. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.
