Science 20 Chapter 2 Quiz 1.
What happens when a strip of zinc is placed in a silver nitrate solution?

The starting reactant in a single displacement reaction is a pure element such as solid zinc metal as well as an aqueous compound. Aqueous implies that the compound is water-soluble. The reaction will result in products that include a different pure element as well as a new aqueous solution.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
