Iam 14 and i am in 8th grade, and i really like this boy in my science class, and i really wanna ask him out but i don't know if he likes me back, and i am scared that i will get rejected, what do i do?
ik it has nothing to do with what it says

just go up to him and express ur feelings, there is no harm for that.

Explanation:

Do you have a good friendship with him, because it'd be wierd asking someone you barely know so i assume yes.

I'm not that good at relationship stuff but my advice is you should start suttely dropping hints, maybe flirt a little but not to much and to bold to expose yourself.

if you come to the conclusion he does have interest in you shouldn't do it infront of his friends or alot of people because that might embarrass him.

But its most important that you just be yourself, if he doesn't like you for the real you then you shouldn't mess with him because thats gonna end in you getting your heart broken when he sees the real you and doesn't like it.

Cause you deserve someone who loves you and will treat you nice.

Sorry if my advice is terrible i hope it helped.

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%
