Table 7.1: in photosynthesis, green plants convert carbon dioxide and water into glucose (c6h12o6) according to the following equation: 6co2(g)+6h2o(l) → c6h12o6(aq)+6o2(g) estimate δh for the reaction using bond dissociation energies from table 7.1. give your answer in kcal. c6h12o6 has five c−c bonds, seven c−h bonds, seven c−o bonds, and five o−h bonds.

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density

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
