Answer:
The order is
Quartz > Calcium > Ammonia > Chlorine
Explanation:
Among given compounds
Quartz is a covalent compound with extensive bondings and thus it will have highest melting point
Calcium is a metal so it will have strong metallic bonds thus will have high melting point, however less than quartz.
ammonia is a polar molecule with weak hydrogen bond as intermolecular interactions thus will have higher melting point than chlorine
chlorine is a non polar molecule with weak intermolecular london dispersion forces.
Answer:
When Avogadro's law is added to the combined gas law, the ideal gas law results. Unlike the named gas laws, the combined gas law doesn't have an official discoverer. It is simply a combination of the other gas laws that works when everything except temperature, pressure, and volume are held constant i think it is right

Hey there!
Answer: Protons
The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well.
Thank you!
Answer: Option (c) is the correct answer.
Explanation:
A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.
And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.
For a binary solution the expression for relative volatility is as follows.
= 
where, 
= relative volatility of more volatile component i
= vapor-liquid equilibrium concentration of component i in the vapor phase
= vapor-liquid equilibrium concentration of component i in the liquid phase
= vapor-liquid equilibrium concentration of component j in the vapor phase
= vapor-liquid equilibrium concentration of component j in the liquid phase
So, when > 1 then separation by distillation is easier in nature.
Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.
