According to the law of conservation of mass, the total mass of the products of a chemical reaction should equal the total mass of the reactants. In our reaction on a balance, however, the mass went down, from 253.0 g to 250.2 grams. Using the given chemical equation, explain what caused the apparent loss of mass.

Qrepresents joules in the formula

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.
