Apreliminary untested explanation that tries to explain how or why things happen in the manner observed is a scientific

The correct answer will be- scientific hypothesis

Explanation:

A scientific hypothesis is a predicted statement proposed on the basis of previous work related to the scientific question. Therefore, the scientific hypothesis is also known as an educated guess.

A scientific hypothesis is designed in a way that it contains the possibility which explains the natural phenomenon to an extent which could be tested through the experiments.

Since the hypothesis explains the phenomenon without testing which is done later through experiment therefore scientific hypothesis is the correct answer.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

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.
