The answer is NO. It can not be a compound it is an element.
In a component mixture it can be separated physically way from the other.
In element it can be only separated by a way of destroying the compound itself by chemical reaction.
Answer:
Option B. 30 KJ.
Explanation:
The following data were obtained from the question:
Temperature (T) = 5000 K
Enthalpy change (ΔH) = – 220 kJ/mol
Change in entropy (ΔS) = – 0.05 KJ/mol•K
Gibbs free energy (ΔG) =...?
The Gibbs free energy, ΔG can be obtained by using the following equation as illustrated below:
ΔG = ΔH – TΔS
ΔG = – 220 – (5000 x – 0.05)
ΔG = – 220 – (– 250)
ΔG = – 220 + 250
ΔG = 30 KJ
Therefore, the Gibbs free energy, ΔG is 30 KJ.
Answer:
Supersaturated solution
Explanation:
Weren't there any options?
Anyways, the best I can think of right now is a supersaturated solution.
Answer:
Explanation:
Nitrogen has a lone pair of electrons. That would mean that NH3 is minus at the left end in this case.
H

Methane has its Hs 90 degrees (approximately apart.

The pulling forces on the methane cancel each other out. When that happens the chemical is non polar.
