Billions of pounds of urea are produced annually for use as fertilizer. Balance the skeletal equation for the synthesis of urea.
NH3(g) + CO2(g) → CO(NH2)2(s) + H2O(l)
Here, we are going to balance the given equation:
According to law of conservation of mass, 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.
