Phase changes! a. write out the clapeyron equation and explain what it describes. b. write out the clausius-clapeyron equation and explain what it describes. c. calculate the boiling temperature of water at an elevation of 1700 m (approximately the height of boulder, co) where the atmospheric pressure is ~0.83 atm. you may use the fact that water boils at 373 k, 1 atm, and that the enthalpy of vaporization is 6.01 kj/mol.

The answer is c - the principal of original lateral continuity. 

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.
