Water molecules are because the hydrogen atoms are positively charged on one end and the oxygen atoms are negatively charged on one end. molecules that are share electrons equally. sodium chloride (nacl) is an example of a molecule because it is soluble in water. molecules that are are insoluble in water. it is that most molecules formed with nonpolar bonds dissolve easily in water.

Water molecules are polar because the hydrogen atoms are positively charged on one end and the oxygen atoms are negatively charged on one end. Molecules that are nonpolar share electrons equally. Sodium chloride (NaCl) is an example of a polar molecule because it is soluble in water. Molecules that are nonpolar are insoluble in water. It is false that most molecules formed with nonpolar bonds dissolve easily in water.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
