Need to pass first semester!

are reaction 1 and 2 balanced? if the reaction is not balanced, then state how you would balance it. then, provide the balanced equation.

what kind of reaction does each reaction represents?

Answer :

Reaction 1 :

This reaction is a balanced chemical reaction and it is an acid-base reaction.

Reaction 2 :

This reaction is an balanced chemical reaction and it is an double-displacement reaction.

The balanced chemical reaction will be,

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

Reaction 1 :

The given chemical reaction is,

This reaction is a balanced chemical reaction because in this reaction the number of atoms of individual elements present on reactant side are equal to the product side.

This reaction is acid-base reaction in which an acid react with a base to give salt and water as a product.

Reaction 2 :

The given chemical reaction is,

This reaction is an unbalanced chemical reaction because in this reaction number of chlorine, hydrogen and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the and we get the balanced chemical equation.

The balanced chemical reaction will be,

This reaction is a double-displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.
