How is this an improvement on the traditional, paper coffee filters? a: they are less wasteful and more cost effective because they last longer b: a permanent filter is more expensive than a traditional filter c: they contain plastic which does not break down as easily as paper d: the coffee brewed using permanent filters does not taste as good?

In a laboratory, 1.55mg of an organic compound containing carbon, hydrogen, and oxygen is burned for analysis. this combustion resulted in the formation of 1.45mg of carbon dioxide and .89 mg of water. what is the empirical formula for this compound?

The atom fluorine generally will become stable through the formation of an ionic chemical compound by accepting electron(s) from another atom. this process will fill its outer energy level of electrons.
