The following heats of formation are used to find the change in enthalpy for the formation of tin chloride in the following reaction

Sn (s) + 2Cl2(g) --> SnCl4(l)

Sn(s) + Cl2(g) --> SnCl2(l) ; ΔH = -186.2 kJ

SnCl2(s) + Cl2(g) --> SnCl4(l) ; ΔH = -325.1 kJ

What is the change in enthalpy?

Use the drop-down menus to label each of the following changes p for physical change and c for chemical change. the substance changes to a new substance. the original substance can be recovered. the color changes. gas is produced and given off. the substance changes size, shape, or volume.
