Explanation:

Elements that gain electrons will have a negative charge and elements that lose electrons will have a positive charge.

Atomic number of sulfur (S) atom is 16 and its electronic distribution is 2, 8, 6. In order to completely fill its octet sulfur will gain 2 electrons and thus it forms $S^{2-}$ ion.Atomic number of potassium (K) atom is 19 and its electronic distribution is 2, 8, 8, 1. In order to stabilize its octet potassium will lose 1 electron and thus it forms $K^{+}$ ion.Atomic number of boron (B) atom is 5 and its electronic distribution is 2, 3. In order to stabilize its octet boron will lose 3 electrons and thus it forms $B^{+3}$ ion.Atomic number of iodine (I) atom is 53 and it has 7 valence electrons. In order to stabilize its octet iodine will gain 1 electron and thus it forms $I^{-}$ ion.Atomic number of bromine (Br) atom is 35 and it also has 7 valence electrons. In order to stabilize its octet bromine will gain 1 electron and thus it forms $Br^{-}$ ion.

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 :

$k_{c}$ = $\frac{[so2cl2] x [cl2]}{[so2cl2]}$

or, $\frac{\alpha ^{2} }{(1-\alpha)v }$

or, $k_{c}$ = $\frac{\alpha ^{2} }{(1-\alpha) }$ (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 :

$\frac{[so2cl2] x [cl2]}{[so2cl2]}$

or, $\frac{\alpha ^{2} }{(1-\alpha)0.5 }$

$\frac{\alpha ^{2} }{(1-\alpha) }$ = $\frac{\alpha ^{2} }{(1-\alpha) 0.5}$

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%

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
