For each of the following statements label true or false.
1. When ∆ H is positive, energy should be written on the reactant side of a reaction.
2. The reaction will be exothermic when the energy is a product of a reaction. 3. When energy is a product during a chemical reaction, the reaction vessel will feel warm to the touch. 4. The ∆ H of a physical change will be 10 to 100s of times that of a chemical change. 5. When ∆ H is positive, the reaction will be endothermic. 6. When a reaction has a negative ∆ H, the reaction vessel will feel warm to the touch.
