You are writing energy balances for a compound for which you cannot find heat capacity or latent heat data. all you know about the material are its molecular formula (c7h12n) and that it is a liquid at room temperature and has a normal boiling point of 200°c. use this information to estimate the enthalpy of the vapor of this substance at 200°c relative to the liquid at 25°c.

The answer to your question is c. mitochondria.

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.
