Based on the chemical formula, what type of compound is sodium fluoride (NaF)? Why? A. Sodium fluoride is a covalent compound because it contains multiple nonmetals, sodium and fluorine. A metallic compound would have multiple metal atoms bonded to each other.

B. Sodium fluoride is an ionic compound because it is composed of a positive and negative ion (metal and nonmetal). A metallic compound would have multiple metal atoms bonded to each other.

C. Sodium fluoride is a metallic compound because it is composed of a mixture with metal ions. An ionic compound would contain only two elements, a metal and nonmetal.

D. There is not enough information provided to determine the type of bond for sodium fluoride.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

what is the question?

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
