A scientist is studying which flower color attracts the most bees. To do this, the scientist releases a group of ten honey bees into a chamber with white walls. The chamber contains potted flowers of the following varieties: yellow daffodils, red roses, white daisies, purple asters, and orange lilies. The results of the experiment is shown in the table below:
Flower Number of Visits in 30 Minutes
yellow daffodils 12
red roses 34
white daisies 19
purple asters 28
orange lilies 30
From the data, the scientist concludes that bees prefer red flowers. Are the scientist's conclusions valid?
A.
No, the honey bees showed relatively the same interest in all of the flowers except the daffodils.
B.
Yes, the honey bees visited the red roses 34 times during the experiment, which was 4 more times than the next popular flower, the orange lily.
C.
Not necessarily; the honey bees may have been attracted to traits other than flower color.
D.
Yes, bees are always attracted to the brightest colored flower, which is why there are very few kinds of white flowers.

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%

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
