1. How much energy (in calories and in Joules) will it take to raise the temperature of 75.0 g of water from 20.0 to 55.0 °C? ( Specific Heat = 1 cal/(g°C) and 4.184 J/(g°C))
A. 2630 cal and 630. J
B. 2630 cal and 1.1 x 104J
C. 1.1 x 104 cal and 2630 J
D. 630. cal and 2630 J
E. None of these are correct.

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
