and have excess of the other when the reaction goes to completionb.The reactant that you have less of is called the limiting reagent, and the one that you have too much of is said to be had in excess2. Percent Yielda.b.Theoretical yield is how much of your products that should be formedc.Both yields are measured in gramsNow answer:1.If a student in the lab reacts 8.2 moles of Magnesium with 3.6 moles of Oxygen gas, how many grams of Magnesium Oxide are formed? If the student actually forms 165.3 g of MgO, what is the percent yield?2.Hydrochloric acid and Sodium Hydroxide are common strong acids and bases (respectively) to be used in chemical reactions. If 18 grams of Hydrochloric acid are reacted with 36 grams of Sodium Hydroxide to bring the reaction to completion, how many atoms of Sodium are formed in the Sodium Chloride compound? How much HCl is left over? . Answers: Part 1: Part 2: Part 3: 1. 2, 1, 2 1. 80 g 1a. 288 g; b. 57.4% 2. 1, 1, 1, 1 2. 3.011x10^23 atoms 2a. 3.011x10^23 atoms; b. None 3. 2, 25, 16, 18 3. 4.36x10^-8 mol Part 4: C 2 H 6 0
Combustion: Combustion : Placing an organic compound in an excess of oxygen and adding heat to form water and carbon dioxide. 1. Things to know a. When given the resultant amounts of carbon dioxide and water, assume they are out of 100 grams. b. All of the carbon from the initial organic compound goes to form all of the carbon dioxide; all of the hydrogen goes to form water. i.
