Option (d) is the correct answer.
- According to the law of conservation of mass,
"The mass of an isolated system can neither be created nor be destroyed but can only be transformed from one form to another form." - It means that the mass on the left-hand side of the equation will be equal to the mass on the right-hand side of equation.
→ Now, using this definition and checking all the options we see,
- Option (a) - Here, 6 green atoms are given in the left-hand side. However, on the right-hand side 3 green atoms and 3 purple atoms are given.
Definitely we can say that this is not balanced as the mass of the green and purple atoms will be different.
Therefore, left-hand side and right-hand side are not balanced. - Option (b) - Here, 1 green atom is present and 1 purple atom is present on the left-hand side. However, on the right-hand side 2 purple atoms are present.
Definitely we can say that this is not balanced as the mass of the green and purple atoms will be different.
Therefore, left-hand side and right-hand side are not balanced. - Option (c) - Here, 3 green atoms are present on the left-hand side. However, on the right-hand side 3 purple atoms are present.
Definitely we can say that this is not balanced as the mass of the green and purple atoms will be different.
Therefore, left-hand side and right-hand side are not balanced. - Option (d) - Here, 3 green atoms are present and 3 purple atoms are present on the left-hand side. On the right-hand side 3 purple atoms are present and 3 green atoms are present.
Definitely we can say that this is balanced as the mass of the green and purple atoms on both sides are same.
Therefore, left-hand side and right-hand side are balanced.
∴ Option (d) is the correct option.
