Why burning of candle is a chemical change?

A

Change is mass

B

Formation of new products

C

Original properties are changes

D

All of above

Dear student 

When you light the candle, the wax present near the wick will melt. Wick absorbs the liquid wax. This wax vapor near to flame burns and gives new substances like Carbon Dioxide, Carbon soot, water vapours, heat and light. This is an irreversible change

When we light the candle wax acts as fuel which is a chemical substance called carbon. Here, x=n,y=2n+2. From the above explanation we can say that formation of new products (carbon dioxide and water) takes place, by the addition of oxygen mass of product will increase and original properties of wax will change .
