What do the coefficients located before certain molecules in each chemical equation represent?

Chemistry
1 answer:
olga55 [171]3 years ago
6 0
It represents the number of moles required of that molecule to balance the chemical equation, which means to have the reaction chemically happen and goes to completion.

For example:
CH4 + O2 --> H2O + CO2     that is not balanced

with the coefficients located
CH4 + 2O2 --> 2H2O + CO2    now with the coefficients the number of oxygen and hydrogen on each side are equal

Which of the following metals (M) will form an ionic compound with nitrogen with the general formula M3N2? Hint: Think about how
Basile [38]

Answer:

See explanation

Explanation:

The question is incomplete but i will try to give you all the necessary guide that you need in order to answer the question.

When compounds are formed, atoms exchange valency. The valency of nitrogen is three while that of the metal is two. The exchange yields M3N2.

If the compound has been specifically mentioned to be a metal, then it must be a group two element. It could be any of Mg, Ca, Sr, Ba or Ra. I did not mention Be here because most of its compounds are covalent.

This will help you to answer the complete question.
