If the decomposition of 0.0150 mol KCIO3 produces 1.80 g KCl, what is the percent yield? The molar mass of KCl is 74.55 g/mol. 2KCIO3(s) + 302(g) + 2KCI(S). (1) 0.83% (2) 83% (3) 90% (4) 62% (5) No answer is correct A Moving to the next question prevents changes to this answer.

Using this reversible reaction, answer the questions below: n2o4 2no2 (colorless) (reddish-brown) -as the temperature increased, what happened to the n2o4 concentration? -was the formation of reactants or products favored by the addition of heat? -which reaction is exothermic? right to left or left to right? -if the change of enthalpy of this reaction when proceeding left to right is 14 kcal, which chemical equation is correct? n2o4 2no2 + 14 kcal n2o4 2no2, hr = +14 kcal n2o4 + 14 kcal 2no2 n2o4 2no2, hr = -14 kcal
