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

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
