1. explain why water is the universal solvent. complete sentence, and use the word solubility or dissolve.

2. what is a polar molecule? explain. use the words positive, negative, and charge.

3. which end of water molecule is negative? which end is positive?

1. Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.

2. In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.

3. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutralmolecule has a positive area at one end and a negative area at the other, it is a polar molecule.

Please try to put this in your own words because I gathered this from a website, and dont want you to get in trouble for plagiarism.
