Why is water considered a polar molecule? a. the oxygen is found between the two hydrogens. b. the oxygen atom attracts the hydrogen atoms. c. the oxygen end of the molecule has a slight negative charge, and the hydrogen end has a slight positive charge. d. both hydrogens are at one end of the molecule, and oxygen is at the other end?

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

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.
