Â© Ted French. Definition: A function is a preset formula in Excel and Google Spreadsheets. Like formulas, functions begin with the equal sign (=) followed by the function's name and its arguments. The function name tells Excel what calculation to perform. The arguments are contained inside round brackets.
Best Answer: Look for molecular symmetries. Symmetrical molecules such as methane, carbon dioxide, carbon disulfide, and borane (BH3) are nonpolar. Asymmetric molecules such as water, ammonia, and acetone are polar.
Molecules can either be polar or nonpolar depending on the arrangement of bonds producing a net dipole. Water is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole.Synonym: 1  dipole.ater is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other.
