Answer 1

Step-by-step explanation

Let us first define the different types of reaction.

A combination reaction is one in which two reactants combine to form a single product.

`2Na+O_2\rightarrow Na_2O_2`

A decomposition reaction will be one in which a reactant breaks down into two or more products.

`2HCl\rightarrow H_2+Cl_2`

A simple displacement reaction will be one in which a reagent, which is in its natural state, displaces one element bound to another. As a product, we will have the previously linked element now in its free form.

`Mg+MnCl_2\rightarrow Mn+MgCl_2`

In a double displacement reaction two linked elements move past each other and take each other's place.

`NaF+KBr\rightarrow NaBr+KF`
