Burning of magnesium strip in air isA. Combination reactionB. Displace

1.	Burning of magnesium strip in air isA. Combination reactionB. Displacement reactionC. Double displacement reactionD. Decomposition reaction
Answer» OPTION A, Combination reaction Reason: Combination reactions are those reactions that have two or more reactants that join together to form a single product. If you look at the CHEMICAL equation of the burning of Magnesium, I.e, 2Mg + O2 ----> 2MgO You can see two reactants (Mg & O2) but a single product (Magnesium OXIDE/ MgO).

Answer»

OPTION A, Combination reaction

Reason: Combination reactions are those reactions that have two or more reactants that join together to form a single product.

If you look at the CHEMICAL equation of the burning of Magnesium, I.e,

2Mg + O2 ----> 2MgO

You can see two reactants (Mg & O2) but a single product (Magnesium OXIDE/ MgO).
