Unformatted text preview: Chem 171 Quiz Version A 1. Predict whether a reaction will occur in the following case. If there is a reaction write the molecular equation, complete ionic equation, net ionic equation and identify any spectator ions. Show the states. Lead nitrate + potassium iodide Pb(NO 3 ) 2 (aq) + 2 KI (aq) 2 KNO 3 (aq) + PbI 2 (s) Pb 2+ (aq) + 2 NO 3- + 2K + + 2I- (aq) 2K + (aq) + 2 NO 3- (aq) + PbI 2 (s) Pb 2+ (aq) + 2I- (aq) PbI 2 (s) K + and NO 3- are spectator ions 2. Ethanol (C 2 H 5 OH) is produced by the fermentation of glucose. The balanced equation is: C 6 H 12 O 6 (aq) 2 C 2 H 5 OH (aq) + 2 CO 2 (g) 1) How is rate of formation of ethanol related to rate of consumption of glucose. 2) Write this relationship in terms of [C 6 H 12 O 6 ] / t and [C 2 H 5 OH] / t According to the balanced equation, 2 mol of ethanol are produced for each mole of glucose that reacts. Therefore the rate of formation of ethanol is twice the rate of consumption of glucose....
