1. What is the temperature at which this substance condenses from a gas to a liquid? 2. Between what two temperatures is this substance in the liquid phase?

3. Clearly label where on the diagram the substance is a solid.

4. If you were heating this substance as it was melting, what is the heat energy doing at that time?

5. What phase of matter does the diagram represent?

They are all solids.

Polymerization reaction

You can find the answer from the answers.com

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
