Please Help! Will Mark Brainliest! 32.5 grams of NaOH (sodium hydroxide) reacts with an excess of CO2 (carbon dioxide). 2NaOH(s) + CO2(g) -> Na2CO3(s) + H2O(I)

(a) What is the theoretical yield of Na2CO3 in grams? Answer is 43.1g but work must be shown.

(b) If 16.45 g of Na2CO3 is formed, what is the percent yield? Answer is 38.2%, but work must be shown.

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
