The diagram below shows four objects in the solar system which have equal masses. Which of these pairs of objects exerts the least gravitational force on each other? (3 points)
Object 1 and Object 3
Object 4 and Object 3
Object 1 and Object 2
Object 4 and Object 2

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)
