Consider the following reversible reaction. C(s) + O2(g) <-> CO2(g) What is the equilibrium constant expression for the given system? - ANSWERCO2/O2 The following reaction occurs in a car's catalytic converter.2NO(g) + 2CO(g) N2(g) + 2CO2(g)Which answer best describes the reducing and oxidizing processes in this reaction? NO and CO are both reducing agents. NO and CO are both oxidizing agents. The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds. The oxidation state of nitrogen in NO changes from 0 to +2, and the oxidation state of carbon in CO changes from +4 to +2 as the reaction proceeds. - ANSWERD The cryosphere is part of which sphere of the Earth system? - ANSWERhydrosphere Which task most likely involves a calculation that uses moles? - ANSWERdetermining the number of atoms in a jar of liquid Consider the chemical reaction in equilibrium. H2 + I2 + heat <-> 2HI What will happen to the chemical equilibrium if the temperature of the system is increased? - ANSWERThe direction of the chemical equilibrium will shift to the right, favoring the forward reaction. Which is a difference between the Paleozoic and Mesozoic era? - ANSWERAnimal complexity increased during the Paleozoic while
