Name and amount of each element in the molecule AgNO3
Ag - Silver - 1
N - Nitrogen - 1

What is color change, production of gas, or formation of a solid?
Covalent bond in which the electrons are not shared equally.
What is a polar covalent bond?
Reason water molecules are polar
What is the electrons are attracted to Oxygen more than the hydrogen, making O to have a slightly negative charge and H to be slightly positive
