Consider the reaction au(oh)3 + hl — au + 12 + h2o.
label the half-reactions as oxidation (use "o") or reduction (use "r").
21 +2 +2e
aut3 + 3e → au

2l- = l2 + 2e- (O)

Au+3 + 3e- = Au (R)

Explanation:

I just answered the question.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
