Assume that your empty crucible weighs 15.98 g, and the crucible plus the sodium bicarbonate sample weighs 18.56 g. After the first heating, your crucible and contents weighs 17.51 g. After the second heating, your crucible and contents weighs 17.50 g. Answer the following questions based on this information.

Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+B D →> Reaction 2 gives product D. The following facts are known about the two reactions: • Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑
