PLEASE HELPP!! CALORIMETRY CHEMISTRY A 20.0 g lead ball is heated in a Bunsen burner to 705 degrees celsius. It is then dropped into a 500.0 g water bath. What is the initial temperature of the water if the final temperature is 35 degrees celsius? The C of lead is 0.13 J/g degrees C.

The answer to this is the 3rd choice!

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.
