In a science experiment showing the splitting of water into Oxygen and hydrogen, two inverted test tubes of water were placed over the site of the reaction. How can you tell which one was catching the oxygen and which one was catching the hydrogen? A. The hydrogen is a positive ion and will be located close to the negative terminal of the battery.

B. The oxygen is a negative ion which will be located next to the negative terminal of the battery.

C. There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.

D. The hydrogen, being a smaller atom, will take up less space than the oxygen. It will push the water down less.

particle   p is an electron and particle q is a neutron

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.
