Please help! The effects of acid mine drainage may vary drastically between dry and wet seasons. If a stream with AMD contamination undergoes considerable evaporation, explain how this will affect the pH of the stream. Will this affect the precipitation of Fe(OH)3 (assuming adequate limestone is present)? If so, explain how. Explain how temperature changes could affect the precipitation of Fe(OH)3.

the answer is the first option

explanation:

just googled it m8. not that hard

lol

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

it's c (engineer's do their work with mechanical stuff not on any living being)
