Be + 2HCI BeCl2 + H2 The theoretical yield of beryllium chloride, BeCl2, was 10.7 grams. If my actual yield was 4.5 grams, what is the percent yield?

[a] 10.7%
[b] 30.2%
[c] 42.0%
(d) 29.6%

the answer is b & c i believe : )

idk what the question is about

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.
