this looks like an acid-base neutralization. what do you think--is this reaction likely to release energy or absorb energy?

anonymous · Answer

hmm i think absorb?

anonymous · Answer

what does your book say about "neutralization reaction"? do you know how to estimate/find the reaction enthalpy?

anonymous · Answer
