1. The neutralization reaction between hydrochloric acid and calcium hydroxide produces calciumchloride and water.2 HCI + Ca(OH)2 ®2 H2O + CaC2If 75 grams of Ca(OH)2 is used in the reaction, determine the following:a. Number of moles of HCI needed to completely react with Ca(OH)2.b. Mass of CaCl2 formed in the reaction.2. The corrosion of aluminum in cookwares is prevented as the aluminum metal reacts withoxygen in the air, producing a protective coat of aluminum oxide.a. Balance the equation:_Al +O2 _Al2O3b. How many grams of oxygen gas will react with 25.0 grams of aluminum?c. How many grams of aluminum oxide will be produced by the reaction in letter b?d. What is the percent yield if the actual yield is 36.4 grams?3. Thermite welding is an exothermic reaction, which produces molten iron that permanentlybinds metals as it cools. The process does not require heat or electricity. Aluminum powder issimply mixed with ferric oxide powder. The reaction is accompanied by a release of heat, andproduces aluminum oxide and molten iron. The equation shows:2 Al + Fe2O3 OAl2O3 + 2 FeIf 55.0 grams of aluminum powder is mixed with 75.0 grams of ferric oxide, which of the twosubstances is the limiting reagent? The excess reagent? How many grams of molten iron (Fe)will be produced?
