Which of the following is not the same as 2.97 milligrams? 0.297 kg, 0.00297 g, 0.297 ch

              0.0000297 Kg is not the same as 2.97 mg.

Converting 2.97 mg into Kg:

As,

                             1 mg is equal to  =  1.0 × 10⁻⁶ Kg

So,

                        2.97 mg will be equal to  =  X Kg

Solving for X,

                      X =  (2.97 mg × 1.0 × 10⁻⁶ Kg) ÷ 1 mg

                      X =  2.97 × 10⁻⁶ Kg

Or,

                      X =  0.00000297 Kg

Hence, 0.0000297 Kg is not the same.

Converting 2.97 mg into g:

As,

                             1 mg is equal to  =  0.001 g

So,

                        2.97 mg will be equal to  =  X g

Solving for X,

                      X =  (2.97 mg × 0.001 g) ÷ 1 mg

                      X =  0.00297 g

Hence, 0.00297 g is the same.

Converting 2.97 mg into cg:

As,

                             1 mg is equal to  =  0.10 cg

So,

                        2.97 mg will be equal to  =  X cg

Solving for X,

                      X =  (2.97 mg × 0.10 cg) ÷ 1 mg

                      X =  0.297 cg

Hence, 0.297 cg is the same.

here we have to get the change of moles on decrease the volume of the reaction in gas phase.

the   per the given options it will decrease by (d) 11-50%

we know, on decreasing the volume of the gas phase reaction the reaction moves to the product side.

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:                   1 - α               α               α           = 1 + α

(concentration = moles/volume, as volume is 1 l)

(where α is the degree of dissociation)

now the dissociation constant in terms of concentration is :

=  

or,

or,   = (at v = 1l)

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:               (1 - α)/0.5           α/0.5         α/0.5       = (1 + α)/0.5

thus, the dissociation constant in terms of concentration is :

or,  

=  

so, the change of 1 : 1/0.5

or, 1: 2

thus it will decrease by 50%.

or, as per the given options it will decrease by 11-50%

its first and third is your answer i did the qustion the fourth isnt right
