Answer:
D
Explanation:
Well it clearly had two hydrogens and one oxygen hence H2O,, and valence electrons are shared between the the atoms not transferred which makes it an covalent bond. As for the polar part, I'm not sure how to explain it well, but I has something to do with partially negative and positive charged atoms.
we are asked in this problem to determine the mass of a liquid in a small container. In order to determine the mass, we use an analytical balance for greater accuracy by first weighing the whole system (liquid+beaker). Then transfer the liquid to another container and completely dry the beaker (wash and dry). measure the weight of the beaker. The mass of the liquid is equal to the mass of the system minus the mass of the beaker.
