In the diagram, which of the following represents the activation energy?

"electrical energy" transforms to "thermal energy".hope my answer has you : )

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.   

Elements that have complete valence shells are found in group 18, also known as the noble gases. these gases possess the stable octet, and are neon, radon, xenon, etc.
