Find the volume of C2H2(g) at STP produced when 4.50 mol of H20 react completely with CaC2? CaC2 (s) + 2 H20 (1) - CH2(g) + Ca(OH)2 (aq).​

The answer is conduction

The answer is c. risk

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.
