The rate constant for the beta decay of thorium-234 is 2.876 x 10 -2 / day. What is the half-life of this nuclide?
a. 48.19 days
b. 1.220 days
c 0.693 days
d. 24.10 days

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.

i think its 100

i hope this !
