Determine the heat given off to the surroundings when 9.0g of aluminum reacts according to the equation 2AI + Fe,O,Al,O;+ 2Fe, AH°, n-849 kJ/mol
Which change happens when a substance melts? O Heat energy overcomes the forces of attraction between the molecules of the substance, so the molecules can move more freely. O The vibration of the molecules produces enough heat to weaken the forces of attraction between the molecules of the substance. O The molecules of the substance move farther apart, which pulls on the intermolecular bonds between them. O Heat energy forces the molecules of the substance farther apart until the rigid structure of the solid breaks.
