Need to pass this to the 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?

Reaction 1 is balanced but 2 is not balanced , the balance equation are :

1.

2.

Explanation:

Balanced Equations : These are the equation which follows the law of conservation of mass .

The total number of atoms present in reactant is equal to total number of atoms present in product.

1.

This is acid - base type reaction where

act as Acid

act as weak base

Reactant : ,

Number of atoms of :

C = 2 () + 1 ()

   = 2 + 1

   = 3

H  = 4() + 1 ()

     = 4 + 1

       5

O = 2() + 3 ()

    = 5

Na = 1 ()

     = 1

Product :  , ,

Number of atoms :

C = 1() + 2()

   = 1 + 2

   = 3

H = 2() + 3()

   = 2 + 3

   = 5

O = 1() + 2()

        +2(

    = 1 + 2 + 2

    = 5

Na = 1(

     = 1

Number of Na =1 , C = 3 , H= 5 and O =5 in both reactant and product , so it is a balanced reaction

2.

This is double displacement reaction .

Check the balancing in both reactant and products should be :

Na = 2

H = 2

Ca = 1

C = 2

O = 6

Cl = 2
