Question

I REALLY NEED HELP GUYS

Marcia is given an incomplete chemical equation that includes the number of nitrogen atoms present in the products of the reaction. How can she conclude that the reaction started with three nitrogen atoms?

Answer 1

There would have to be three nitrogen atoms In the products. The law of conservation of matter states that the amount of substance before a reaction occurs should be the same as the amount of substance after the reaction.

(Just did this on edgenuity)

Answer 2

She can conclude that the reaction started with 3 nitrogen atoms, because in the question, it said that it includes the number of atoms for the product.

Replace the answer with 3, and finish the equation, and you will get the answer

hope this helps
