What does your textbook say about 1.1.2 Balanced Chemical Equations?
Recall the law of conservation of mass that you studied in Class IX; mass can neither be created nor destroyed in a chemical reaction. That is, the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. In other words, the number of atoms of each element remains the same, before and after a chemical reaction. Hence, we need to balance a skeletal chemical equation. Is the chemical Eq. ( . ) balanced? Let us learn about balancing a chemical equation step by step. The word-equation for Activity . may be represented as –
