Which type of reaction is NaCI + AgNO3 NaNO + AgCI?
O synthesis
O decomposition
O oxidation
O replacement

replacement

Explanation:

There are two types of replacement reactions.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

The given reaction is double replacement reaction because anion and cation of both reactants exchanged with each other.

Other options are incorrect because,

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
