Two iron blocks of equal size and mass are kept in contact with each other as shown in the figure. The block on the left side has been heated to 120°C and placed in contact with the block on the right side which has been cooled to 20°C. What are the temperatures of the two blocks once they have reached thermal equilibrium? ANSWER ASA 3-5 SENTENCES

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
