The two resonating structures of Nitrous Acid are shown below. Lone pair of electrons, single and multiple bonds and non zero formal charges (red color) are also specified.
Among these two structures the structure on the left lacking formal charge is the most stable form. The instability of second resonating structure is due to the fact that it contains two formal charges (the lesser the number of formal charges the greater is the stability). Secondly in this structure one oxygen atom is having +1 formal charge. Oxygen being more electronegative feel hostile towards positive formal charge.
Hydrogen fusion is the answer. It is also known as <span>hydrogen burning. </span>
The liquid would evaporate
According to the reaction equation:
CaF2(s) ⇄ Ca2+(aq) + 2F-(aq)
So the Q expression will be = [Ca2+][F-]^2
and we will neglect the [ CaF2] as it is solid
so, by substitution:
when we have [Ca2+] = 0.01
and [F-] = 0.015
Q = 0.01 * (0.015)^2
= 6.3 x 10^-2
by comparing Q value which is 6.3 x 10^-2 and Ksp value which is 1.8 x 10^-5
So, we can see that Q > Ksp
-that means precipitation will form as ion concentration are greater than
equilibrium concentration So, the reaction will proceed in reverse to achieve
equilibrium . and the solution will be then supersaturated.
Answer:
Image result for Which hydrogen is an unsaturated hydrocarbon ?
Alkenes have the general formula CnH2n, and are examples of unsaturated hydrocarbons. The presence of a double bond compound's structure causes there to be two fewer hydrogen atoms in the molecule than there are in an alkane with the same number of carbon atoms.
