A piece of metal of mass 22 g at 110°C is placed in a calorimeter containing 40.5 g of water at 22°C. The final temperature of the mixture is 62.8°C. What is the specific heat capacity of the metal? Assume that there is no energy lost to the surrounding.

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
