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.
Non-Polar: A molecule that does not posess a dipole because of the arrangement of molecules. This affects the rate of dissolving and solubility because of the intermolecular forces of particles. Polar compounds dissolve in Polar solvents, Non-Polar compounds dissolve in Non-Polar solvents.
