Number of problems:	1  5  10  25  50
Chemical equations are:	Balanced  Unbalanced  A mix of both balanced and unbalanced equations
Type of problems:	Calculate heat absorbed or released when given amount of substance  Calculate amount of substance required when given heat (not with limiting reagents)  A mix of both types of problems
