A current of 0.85 A is passing through a 27 12 resistor for 1 hour. b. What power is the resistor using?

c. How much thermal energy is the resistor generating?

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.
