Energy
Energy of Energy of
Reactants Products
A.

B. The reaction is endothermic.
C. The reaction requires a catalyst.
D
The reaction has a low activation energy.

a. hope i'm right

explanation:

po-215 i got it right on the quiz

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.

c) should be the answer.
