Answer:
calcium hydroxide
lithium phosphate
ammonium sulfide
AgNO3
Explanation:
A polyatomic ion refers to an ion composed of two or more atoms in the ion. In the compounds mentioned, each contains at least one poly atomic ion.
AgNO3 contains NO3^- as its polyatomic ion
calcium hydroxide contains OH^- as its polyatomic ion
lithium phosphate contains PO4^- as its polyatomic ion
ammonium sulfide contains NH4^+ as its polyatomic ion.
The charge of a nucleus is neutral, meaning it’s zero
the positive charges of an atom equal the negative charges so the atom has a neutral charge
the answer is B. 2
because there is 2 iron on the right side so you need another two on the left side to balance it out
