How can you gauge the efficiency of a reaction carried out in the laboratory?

the answer is true.

this statement is true.

Bthats what im doing to and i figured it out it is b

Adialysis unit requires 78.5 l of water.the estimated digit is 5. 

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.
