The biological compounds that are nonpolar and insoluble in water are lipids. It is a group of molecules that are naturally occurring which includes sterols, waxes, fats, fat-soluble vitamins and the like. These molecules are nonpolar molecules so basically the cannot be dissolved in a polar solvent like water.
<h2>Answer : The order of conductivity from most conductive to least is this - </h2><h2>Calcium bromide

, Potsassium bromide (KBr), Benzoic acid

and last is sugar.</h2><h3>Explanation : </h3>
When dissolved in water
produces three ions namely;
and
which acts as best conductor amongst the given choices.
Next is potassium bromide when dissolved in water generates only two ions which are
and
and acts as an conductor.
Benzoic acid
, is a weak acid and is slightly ionized so it acts as an weak conductor.
Sugar is a non ionized compound so it is anon conductor.
Answer:
See explanation
Explanation:
The third and fourth elements in the first transition series are vanadium and chromium. They contain 23 and 24 electrons respectively.
In universe L, the electron configuration of vanadium is;
[X] 3d3 4s2
In universe L, the electron configuration of chromium is;
[X] 3d4 4s2
The electron configuration of chromium has to change since there are four instead of five d orbitals in universe L.
The answer is select a habitat !
Answer:
0.2042 M is the original concentration of
(aq) in the titrating solution.
Explanation:
Mass of
= 0.217 g
Moles of 
1 mole of
have 2 mole of As and 1 mole of
have 1 mole of As.
So, from 1 mole of
we will have 2 moles of 
Then from 0.001096 mol of
:
of 

According to reaction, 1 mole of
reacts with 2 mole of cerium (IV) ions,then 0.002192 mol of
of cerium (IV) ions.
Volume of the acidic cerium{IV) sulfate = 21.47 ml =0.02147 L
1 mL = 0.001 L

![[Ce^{4+}]=\frac{0.004384 mol}{0.02147 L}=0.2042 M](https://tex.z-dn.net/?f=%5BCe%5E%7B4%2B%7D%5D%3D%5Cfrac%7B0.004384%20mol%7D%7B0.02147%20L%7D%3D0.2042%20M)
0.2042 M is the original concentration of
(aq) in the titrating solution.
