Answer: An Element
Explanation:
An element is a substance that cannot be split into smaller substance. It is made up of one kind of atom and can exist either as molecules (e.g nitogen) or an atom (e.g argon).
Balanced equation :
3H₂+N₂⇒2NH₃
<h3>Further explanation</h3>
Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Unbalanced⇒the number of atoms from both sides (reactants and products) is not the same
H₂+N₂⇒NH₃
H=2(left), H=3(right)
N=2(left), N=1(right)
Balanced ⇒ the number of atoms from both sides (reactants and products) is equal
3H₂+N₂⇒2NH₃
H=3x2=6(left), H=2x3=6(right)
N=2(left), N=2x1=2(right)
