If excess of C2H4 is combined with 122.0 g of Br2, as the following reaction, C2H4(g) + Br2 (l) ---> C2H4Br2 (l) What mass of C2H4Br2 can be produced in this reaction

You have 22.2 g of the compound C2Hx, where x is the maximum number of hydrogens that can fit around two carbon atoms and still create a stable Lewis dot structure. If you allow all of this sample to react with excess oxygen and then allow the products to cool to room temperature, how many moles of liquid product will you have?

What was the actual amount of magnesium oxide (MgO) produced if the percent yield was 81.7% when 62.7 g of magnesium metal (Mg) reacted with an excess amount of carbon dioxide (CO,) ? 2 Mg + CO2- 2 MgO + C (Molar mass (in g/mol) of: Mg 24.3;C = 12.01;0 = 16.0)

How many more kilograms of O2, with respect to C,H12O6, is required for this amount of product to be made? 99 COH12 0u + 60z- OCOz + H20 A: 0.32 9.81x 1025 mol CO2 83 Chemistry I © 2020 F'20/S'21 WORKSHEET 4

5. 2Fe(OH);(s) + 3H,SO4(ag) → Fe2(SO4);(ag) + 6H;0(I) classify: If 2.4 g Fe(OH)3 and 3.3 g H2SO4 react and make 4.5 g Fe2(SO4)3, g H20 are made also. Find theoretical yield of Fe2(SO4)3 in a reaction of 24.1 mol Fe(OH)3 and 30.5 mol H2SO4 : The 24.1 mol Fe(OH)3 are enough to form mol Fe2(SO4)3. The 30.5 mol H,SO4 are enough to form mol Fe2(SO4)3. The limiting reagent in the mixture is The theoretical yield of Fe2(SO4)3 is moles If only 8.2 mol Fe2(SO4)3 Was isolated, the percent reaction yield is %
