Answer 2

In a chemical reaction,the substance changes.Common example is burning that happens when paper or wood burns!Paper or wood are made of a substance called cellulose,and it is the cellulose that burns.While burning,cellulose takes up oxygen from air and gives two new substances-carbon dioxide and water(in the form of vapour).Also,when burnt in air,carbon forms carbon dioxide and sulphur forms sulphur dioxide.Thus,all these are chemical reaction.
