An example of the hertzsprung-russell diagram is shown above. using this diagram, what can you say about white dwarfs? (hint: notice that the temperature on the x-axis is hotter on the left and cooler on the right.) a. they are very bright and hot. b. they are very bright, but relatively cool. c. they are relatively dim, but very hot. d. they are relatively dim and cool.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
