Workshop Names: 1. A sample of 32.0 g of aluminum hydroxide, AI(OH)s, is mixed with a solution that contains 40.0 g of HCI. They react according to the balanced equation Al(OH)(s) + 3 HCl(aq) â AICMaq) + 3 HJXr) a. Calculate the number of moles of each starting species. b. Identify the limiting reagent Calculate the mass in grams of AICl, that is produced if the limiting reagent reacts completely. c. 2. Aluminum and bromine react together to form the salt aluminum bromide. a. Write the balanced equation for this process. Include the states of all reactants and products b. In the spaces provided below, make a two-dimensional drawing of the submicroscopic particles in the reactants and products: (use for Br, use o for Al) REACTANTS 3. Consider the following reaction: 2 HCI (aq)+Zn(s) - -H2 (g)+ Zn2 (aq) +2 CI (aq) For the reaction between zinc and HCl, please circle the limiting reagent in the each of the following sets of reaction conditions a.) 8.0 g Zn and 0.300 moles of HCI b.) 8.0 g Zn and 0.060 moles of HCI c.)7.85 g Zn and 0.240 moles of HCl
