Unformatted text preview: ________ 2. Stoichiometry a. (6 pts) Balance the following chemical reactions: 1 C2 H6 + _7/2_O2 → _2_CO2 + _3_H2 O _1_ Cl2 O 7 + _1_H2 O → _2_ HClO4 b. (10 pts) Consider the reaction taking place in water: Ca(OH)2 (s) + 2 HCl (aq) → CaCl2 (s) + 2 H2 O How many grams of calcium hydroxide [Ca(OH)2 ] must be added to obtain complete reaction of 0.200 moles of HCl? Show your complete calculation. (You may round atomic weights to one decimal place.) the relative molecular mass of Ca(OH) 2 is (40.08) + 2(16.0 + 1.01) = 74.1 gm/mol. Thus ⎛ 74.1gm ⎞⎛1mo...
