the 3 pages deal with limiting reactant and percentage yield.
the mixture starts out as a bright blue and when spinning in the
cup smokes ans starts to tirn a black color and the end result is a
brown color. then the funnel part was a light blue color.
1. Weigh approximately 7.0 g of CuCl2 and place them in the 100 ml beaker. Record the exact mass in the data table below. Note the appearance of the CuCl2 crystals...

The theoretical yield (Sec. 6.9) for a chemical reaction is the maximum amount of a product that can be obtained from given amounts of reactants. Calculate the theoretical yield, in grams, of aluminum chloride that could be produced from 5.27 moles of aluminum. (Assume that enough Cl, is present.) c. What is the theoretical...
please answer 1 & 2 thank you 1. limiting Reactant - Mass to Mass: Perform two calculations to determine the limiting reactant and amount of product produced. Hydrogen cyanide, a highly toxic compound, is made by the following reaction: 2 CH4(g) + 2 NH3(g) + 3 O2(g) → 2 HCN(g) + 6 H2O(g) What is the limiting reagent with respect to HCN production if 45.4 g of O2 are added to 23.8 g of NH3? (assume CH4 is in excess)...

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...
