You will isolate the [Cu(NH3)4]SO4 H₂O product before you leave the lab on Day #1, but you will not weigh your product to determine the yield until Day #2. Why is it necessary to wait until the next lab period before you weigh the product to determine the yield? O This is a long experiment, and there won't be time to weigh the product before class ends on Day #1. We wait to weigh the product to allow time for any water and/or ethanol to evaporate completely. If the product is "wet", the measured yield will be too high. O It will take several days for the solid to precipitate after we add the ethanol. ○ It is not necessary to wait several to determine the yield. The mass of product isolated can be determined on Day #1.

The stoichiometric equation for the oxidation of bromide ions by hydrogen peroxide in acidsolutions is 2 Br– + H2O2 + 2 H+ → Br2 + 2 H2O ? = ?[H2O2][H+][Br−]If the concentration of H2O2 is increased by a factor of three, by what factor is the rate ofconsumption of Br– ions increased?
MN IN The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCS) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.
