Soluble means that something will "dissolve" in a substance (typically water). This means that the substance is polar (like water)
insoluble is the opposite of soluble. It means that a substance will not dissolve in water. This means this is non-polar

Explanation:
Steroids are biologically very important compounds. They are made up of more that
seventeen carbons. The structure of Steroid is comprised of a fused
cycloalkane ring system. The simplest steroid and the main skeleton of all steroids is
Gonane.
Gonane is made up of four cycloalkane rings i.e. tetracyclic hydrocarbon ring structure. Among these four rings 3 are
cyclohexanes (designated as A, B and C) and one is
cyclopentane (Designated as D). These four rings fuse to form a <span>cyclopentaperhydrophenanthrene.
The Nucleus (Gonane) of steroids along with some derivatives are shown below,</span>
The answer is 14.

Answer:
This will be the balanced half reaction:
NO₂(g) + H₂O (l) → NO₃⁻(aq) + 1 e⁻ + 2H⁺ (aq)
Explanation:
In acidic medium, the redox balance has to be done as this way.
As it is an oxidation, we know that oxidation state has increased.
NO₂(g) → NO₃⁻(aq) + 1 e⁻
Nitrogen in NO₂ acts with +4; in the nitrate, N acts with +5
The nitrogen has released 1 electron.
As we are in acidic medium, we must complete with water, in the same side, as we have less oxygens and in the opposite side, with protons to balance the H. This will be the balanced half reaction:
NO₂(g) + H₂O (l) → NO₃⁻(aq) + 1 e⁻ + 2H⁺ (aq)
