In the chemical equation 2 co(no3)3 + 3 (nh4)2s → co2s3 + 6 nh4no3 , how many nitrogen atoms are on each side of the equation?

6

Explanation:

On the left hand side, we have three nitrogen atoms within the polyatomic ion. You then multiply that by the stoichiometric coefficient (the numbers to the left of a a formula that are used to balance the equation). So it is 2*3=6.

On the right, there are two nitrogen atoms within the formula then multiplied by the stoichiometric coefficient again. 2*3=6

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
