Question

the formula agf would be classified as...
element
compound
mixture

Explanation:

1. An element is a pure substance made of only one type of atom. AgF has two different types of atoms (Ag - silver and F - fluorine), so it's not an element.
2. A compound is a pure substance made of two or more different elements chemically combined in a fixed ratio. AgF is made of silver (Ag) and fluorine (F) atoms bonded together, so it fits the definition of a compound.
3. A mixture is a combination of two or more substances that are not chemically combined. AgF is a single substance with a fixed chemical formula, so it's not a mixture.

Answer:

B. compound
