Answer:
For 1: Nitrogen and hydrogen atoms are unbalanced.
For 2: Hydrogen atom is balanced and oxygen atom is unbalanced.
For 3: Carbon atom is balanced and oxygen and hydrogen atom is unbalanced.
Explanation:
- For 1:
The given chemical equation follows:
[tex]N_2+H_2\rightarrow NH_3[/tex]
On the reactant side:
Number of nitrogen atoms = 2
Number of hydrogen atoms = 2
On the product side:
Number of nitrogen atoms = 1
Number of hydrogen atoms = 3
As, the number of nitrogen and hydrogen atoms are not same on both the sides of the reaction. So, these elements are unbalanced.
- For 2:
The given chemical equation follows:
[tex]H_2O\rightarrow H_2+O_2[/tex]
On the reactant side:
Number of oxygen atoms = 1
Number of hydrogen atoms = 2
On the product side:
Number of oxygen atoms = 1
Number of hydrogen atoms = 3
As, the number of oxygen atoms are not same on both the sides of the reaction. So, this element is unbalanced.
Number of hydrogen atoms are same on both the sides of the reaction. So, this element is balanced.
- For 3:
The given chemical equation follows:
[tex]CH_4+O_2\rightarrow CO_2+H_2O[/tex]
On the reactant side:
Number of carbon atoms = 1
Number of oxygen atoms = 2
Number of hydrogen atoms = 4
On the product side:
Number of carbon atoms = 1
Number of oxygen atoms = 3
Number of hydrogen atoms = 2
As, the number of oxygen and hydrogen atoms are not same on both the sides of the reaction. So, these element are unbalanced.
Number of carbon atoms are same on both the sides of the reaction. So, this element is balanced.
Answer:
Atoms balanced:
Hydrogen (Separate Water)
Carbon (Combust Methane)
Atoms Unbalanced:
Oxygen (Separate Water)
Oxygen (Combust Methane)
Hydrogen (Combust Methane)
Nitrogen (Make Ammonia)
Hydrogen (Make Ammonia)
