Oxidation happens when substances are combined with a electricity b uranium c heat d oxygen

oxygen

Explanation:

The process in which a substance loses an electron in a chemical reaction is called oxidation. ... Oxidation is a combination of elements with oxygen. It's also a reaction of losing electrons and gaining positive charge. The atoms that lost electrons are said to be oxidized.

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.
