Question

Magnesium metal burns in the air with a dazzling white flame. The type of chemical reaction seen is (a) combination reaction (b) decomposition reaction (c) displacement reaction (d) double decomposition

Answer 1

Answer:

[d] double decomposition

Answer 2

Burning of magnesium metal in air with the dazzling white flame is an example of COMBINATION REACTION.

First of all , let's learn about combination reactions:

• Combination reaction is a chemical reaction.

• It is a type of chemical reaction in which different atoms of reactants combine with each other by bonds to produce a product.

• In other words, this is a chemical reaction in which two or more reactants produce products.

Now, let's see the required reaction:

$\boxed{\sf{2Mg + O_{2}\longrightarrow 2MgO + Flame}}$

Here Mg and $O_{2}$ are the reactants which combine with one another to produce Magnesium Oxide (MgO).
