It is important for scientists to know how much energy is given off or absorbed in a chemical reaction. Which options below would indicate an exothermic reaction? delta H = –

delta H = +

Energy is considered a reactant in the reaction: A + B + energy ---> C + D

Energy is considered a product in the reaction: A + B ---> C + D + energy

Energy is released in the reaction.

Energy is absorbed in the reaction.

A,D&E

Explanation:

A, D, E

Explanation:

I got it right fs

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
