Question

2Mg+O2=2MgO Number of reactants=2 number o product

Answer 1

This is a type of decomposition reaction

2mg+o2 =2mgo

In this , no. Of reactants =2and the no. Of products =2

Answer 2

Answer:Magnesium burns in oxygen by producing dazzling white flame and changes into white power. The white powder is magnesium oxide.

Explanation:

Reactants are those substances that undergo a chemical reaction. Here the reactants are Magnesium and Oxygen. Product is the substance(s) formed when the reactants react in the reaction.

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+O2→2MgO

4) It is a chemical combination reaction.

5) In this reaction magnesium and oxygen combine to form a new substance magnesium oxide
