Text Solution

Verified by Experts

Chemical combination :-
1) A reaction in which single product is formed from two or more reactants is known as the chemical combination reaction.
2) Magnesium burns in oxygen by producing dazzling white flame and changes into white power. The white powder is magnesium oxide.
3) `2Mg+O_(2) rarr 2MgO`
4) It is a chemical combination reaction.
5) In this reaction magnesium and oxygen combine to form a new substance magnesium oxide.
6) Another example : Burning of coal is `C+O_(2)rarrCO_(2)`
