HeELP BRAINLIES Question 10
The amounts of two elements X and Y in three samples of an unknown
substance are as follows: 10,0 g X and 10,0 g Yin Sample 1, 18.0 g X and
12.0 g Yin Sample 2, and 6,0 g X and 2.0 g Y in Sample 3. This substance is
-likely a mixture
-likely an element
-either a compound or an element, but cannot be a mixture
-likely a compound

dynamic equilibrium is the answer.

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.
