Compound b contains 92.31% carbon and 7.69% hydrogen. determine the empirical formula of b

CH

Explanation: To calculate the empirical formula of the compound we must first find the number of moles by using the mass of each element.

C= 92.31 g x 1mole C / 12 g C

= 7. 69 moles C

H = 7.69 g H x 1 mole H/ 1 g H

= 7.69 moles H

Next is divide each answer on the lowest number of moles

C = 7.69 / 7.69 = 1

H = 7.69 / 7.69 = 1

So the ratio is 1:1 or CH

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.
