3 Find the AH° for the reaction below, given the following reactions and subsequent AH values: N2H (1) + CH, O(1) CH2O(g) + N2(g) + 3H2(g) 2NH3(g) N H (1) + H2(g) AH = 47.5 kJ 2NH, (g) N2(g) + 3H2(g) AH=57.5 kJ CH2O(g) + H2(g) CH, O() AH = 81.2kJ ​

Which other elements contain the same number of outer electrons as sodium

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.

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
