Answer:
Explanation:
Assume Ksp of 
=
( it is general value ,i took it because not given in question)
molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.
Ksp=solubility product;
Lets molar solubilty of 
is S then
![[Pb^{+2}]=S;](https://tex.z-dn.net/?f=%5BPb%5E%7B%2B2%7D%5D%3DS%3B)
![[SCN^{-1} ]=2S;](https://tex.z-dn.net/?f=%5BSCN%5E%7B-1%7D%20%5D%3D2S%3B)
- A chemical reaction is considered as a process of transformation of chemical reactants into products.
- Chemical reactions involve change in position of electrons or breaking the bonds between atoms to form new molecules. (no change in the elements present).
- Chemical reactions are best described by chemical equations
So the correct answer is B
Answer:
a
Explanation:
A Gamma rays is the best wavelength for an astronomer to use to study the composition of planets and stars
Onic compounds<span> are formed from strong electrostatic interactions between </span>ions<span>, which result in higher melting points and electrical conductivity compared to </span>covalent compounds<span>. </span>Covalent compounds<span> have</span>bonds<span> where electrons are shared between atoms.</span>
H + N = NH3
Hydrogen plus nitrogen is ammonia. This is covalent bond.
