7. Observe the following chemical equations:
H2+0 H20
2N+ 3H22NH
Are the above given equations correct? Explain.
Answers
Answer: When we are writing a chemical equation, we should never forget to balance the equation because when the chemical equation is unbalanced, then the equation is incorrect or incomplete. Therefore, always remember to balance the chemical equation.
Explanation:
The left side will be having two hydrogen atoms and two oxygen atoms.
The right side will be having two hydrogen atoms and one oxygen atom.
In order to balance the oxygen atom, we have to multiply the oxygen atom on the right side by 2. When we are multiplying by 2, the number of hydrogen atoms in the right side becomes four.
Now to balance the hydrogen atom on both sides, we have to multiply the hydrogen atom on the left side by 2.
Finally, the oxygen atom present on both sides becomes two and the hydrogen atoms present on both sides becomes 4.
