1. An experiment studies the effects of an experimental drug on the number of offspring a mother mouse has. 10
female mice are given the drug and then impregnated.
The number of mice in their litters is compared to the
litters of mice that did not take the drug.

In a particular chemical reaction, the energy of the reactants is 30 kj and the energy of the products is 5 kj. 
 the maximum energy of the system is 40 kj. sketch a potential energy diagram for this reaction. make sure to label the energy of the reactants, the energy of the products, the activation energy, and the enthalpy change for the reaction.
