Cyclohexane (c6h12) is a hydrocarbon (a substance containing only carbon and hydrogen) liquid. which of the following will most likely dissolve in cyclohexane to form a solution? ch2cl2hinabrch3ch2ch2ch2ch3

CH₃CH₂CH₂CH₂CH₃

Explanation:

Cyclohexane is a nonpolar compound. There is a rule that states that "like dissolves like" meaning polar is soluble in polar and nonpolar is soluble in nonpolar.

CH₂Cl₂. This compound is polar

HI. This compound is slightly polar (dipole moment = 0.38 D)

NaBr. This compound is ionic (great difference in electronegativity between the atoms).

CH₃CH₂CH₂CH₂CH₃. This compound is nonpolar, and the one that will most likely dissolve cyclohexane.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
