A sixth grade students has proposed the model below to demonstrate the sun's role in the water cycle. what changes would you suggest be made to make the model more accurate.

Explanation:

Question

Dombey sat in the corner of the darkened room in the great arm-chair by the bedside, and Son lay tucked up warm in a little basket

bedstead, carefully disposed on a low settee immediately in front of the fire and close to it, as if his constitution were analogous to that of a muffin,

and it was essential to toast him brown while he was very new.

Dombey was about eight-and-forty years of age. Son about eight-and-forty minutes. Dombey was rather bald, rather red, and though a

handsome well-made man, too stern and pompous in appearance, to be prepossessing. Son was very bald, and very red, and though (of course) an

undeniably fine infant, somewhat crushed and spotty in his general effect, as yet. On the brow of Dombey, Time and his brother Care had set some

marks, as on a tree that was to come down in good time-remorseless twins they are for striding through their human forests, notching as they go

- while the countenance of Son was crossed with a thousand little creases, which the same deceitful Time would take delight in smoothing out and

wearing away with the flat part of his scythe, as a preparation of the surface for his deeper operations.

(from Dombey and Son by Charles Dickens)

Which best expresses the main effect of the description of Dombey and his Son?

O 1. The description shows that Dombey is happier now that Son is here.

2. The description compares Dombey and Son to the twins Time and Care.

O 3.

The description hints that the young will become better men than the old.

O 4. The description suggests that Time and Care affect the old and the young alike.Question

A sixth grade students has proposed the model below to demonstrate the sun's role in the water cycle. what changes would you suggest be made to make the model more accurate.

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%
