QUESTION 25 Will the following solutions produce a precipitate when combined? If so, the precipitate(s) would be Potassium lodide (aq) and Sodium Chloride (aq) Yes, there would be precipitation and the precipitate would be Potassium Chloride. Yes, there would be precipitation and the precipitate would be Sodium lodide. Yes, there would be precipitation and the precipitate would be Potassium lodide. O No, there would not be any precipitate formed.​

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
