A reaction joins two molecules to create one molecule with a strong bond. Which statement is most likely true of this reaction? Hint: delta G = delta H - T delta S A. the reaction is always exergonic
B. the reaction is favorable at higher tempuratures
C. the reaction is favorable at lower tempuratures
D. the reaction is always endergonic

Answerhund's rule;

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.
