consider the following balanced reaction : 2naoh +co2> na2co3 +h2o.

3 moles of naoh and 4 moles of co2 are allowed to react according to the above equation .

(i)which reagent is the limiting reagent?

(ii) what is the maximum number of moles of na2co3 that can be formed

(iii) how many moles of excess reagant remain unreacted? (iv) if the actual mass na2co3 produced was 0.5 mol, what percentage yield of na2co3?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
