What is skeletal chemical equation?

Which is balanced

Which does not contain physical states of reactants and products.

Which is unbalanced but contains physical states and symbols

Which is not balanced due to mass difference on both sides

Q.2) Arrange in proper sequence the steps to balance a chemical equation:-

1) Draw boxes around each formula.

2) Writing symbols of physical states.

3) Count number of each element on both sides of the equation.

4) List the number of atoms of different elements present in the equation.

5) Start balancing with the compound that contains the maximum number of atoms.
