What is a formula class 9th?
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.
For example - NaOH+HCl⟶NaCl+H2O.What are the basic formulas in chemistry?
A chemical formula may be defined as the “Symbolic representation of its composition” or in other words, “A chemical formula of a molecular compound represents the actual number of atoms present in one molecule of the compound”.
For example: H2O is the chemical formula of water, NH3 is the chemical formula of ammonia.What are chemical formula Class 9?
The chemical formula of a compound means the symbolic representation of the composition of a compound.
A chemical formula for a molecule is represented by the group of symbols of the elements that constitute the molecule, and the number of atoms of each element present in one molecule.
