1.	How is the chemical reaction written ? Explain it with suitable example.
Answer» Solution :The burning of magnesium RIBBON in presence of OXYGEN forms magnesium oxide. The reaction is conveniently described by a chemical EQUATION as shown below `underset("REACTANTS")(ubrace(Mg+O_(2))) to underset("Product")(ubrace(MGO))` In the equation, Mg and `O_(2)` undergo chemical reaction are called reactants, and Mgo is known as product which is obtained at the end of the reaction. Reactants are always written on the left side and products are mentioned on the right side of the arrow in the chemical equation. The sign `to` is put between the reactants and products. If more than one reactants are involved in the reaction, then + sign is written between them. Similarly, if more than one products are formed, then also, + sign is placed between them.
