The chemical reaction 2 H2O + energy → 2 H2 + O2 is 1. a synthesis reaction. 2. an endothermic reaction. 3. an exothermic reaction. 4. an ionic reaction.

1) Write the word and symbol equation to show what happens when water is added to Calcium Oxide. 2) Write word and symbol equations for the thermal decomposition of limestone.

Most organic polymers are named based on the monomers used in their production. However, poly (vinyl alcohol) (PVA) is not made from vinyl alcohol, but instead from vinyl acetate that is hydrolized after formation of the polymer.

Explain the relationship between the dissociation of water and the ph of a particular aqueous solution.
