a. 0.45 mol ethanol
b. 1.22 mol ethanol
c. 1.2 × 10-2 mol ethanol
Solution 58E: Step1: We can say that all metals are not equally reactive. That is why, reactive metals can displace less reactive metals from their compounds in solution or molten form. In order to know, which metal is more reactive, several experiments were performed, and finally a series known as the reactivity or activity series was developed.The metals at the top of the activity series are readily oxidized and are less stable whereas those at the bottom of the activity series are least readily oxidized and are more stable. Step2: Let us consider the two reactions given above. Br2aq) + 2NaI(aq) ------> 2NaBr(aq) + I (aq) 2 ------(1) Cl2aq) + 2NaBr(aq) ------> 2NaCl(aq) + Br (aq) 2 ------(2) a) In equation (1), we have seen that, bromine replaces iodine from its salt solution. This indicates that bromine is more reactive than iodine and hence...
