Acertain compound has an empirical formula of ch3. what must be true about this compound?

option B

Explanation:

It has 75% Hydrogen by mass

If we assume CH3 as 100% which is 4 parts.

Then 3 parts corresponds to Hydrogen which is 75% and remains is carbon,25 %

So B is correct answer.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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.
