If element X has an atomic mass of 32 amu, and element Z has an atomic mass of 118 amu, and element U has an atomic mass of 2 amu, what is the
percent by mass of Z in the following?
ZU3X

it is called acid bonding

the answer to your question is c

b. is the answer hoped i        

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.
