For which of the following reactions is δh∘rxn equal to δh∘f of the product(s)?
you do not need to look up any values to answer this question.
check all that apply.

a) 2li(s) + ci2 (g) --> 2licl(s)

b) li (s) + 1/2 cl2 (l) -> licl (s)

c) baco3 (s) -> bao ( s) + co2 (g)

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

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.

the answer is 0.42 is that is an option. this question provides no info
