Which type of reaction is nacl + agno3 → nano3 + agcl? synthesis decomposition oxidation replacement

Answer : The reaction is a type of replacement reaction.

Explanation :

Replacement reaction : In this chemical reaction, a positive cation and a negative anion of the two reactants exchange their places to form two new products.

Decomposition reaction : In this chemical reaction, the larger compound decomposes into two or more smaller compounds.

Synthesis reaction : In this chemical reaction, the multiple reactants combine to form a single product.

Oxidation reaction : It is the process of the loss of one or more electrons or we can say that increases in the oxidation number.

The given balanced chemical reaction is,

This reaction is type of replacement reaction in which a positive cations (sodium and silver) and a negative anions (chlorine and nitrate) of the two reactants exchange their places to form two new products which are sodium nitrate and silver chloride.
