Answer: Option (A) is the correct answer.
Explanation:
According to the Gibb's free energy conditions:
If 
< 0, then reaction is spontaneous.
If > 0, then reaction is non-spontaneous.
If = 0, then reaction is equilibrium.
Since, the given reaction is 
. It denotes that liquid state of fluorine is changing into gaseous state. And, the boiling point of fluorine is very low.
Therefore, at low and high temperature fluorine is a gas. Hence, the reaction is spontaneous in nature.
Thus, we can conclude that the statement at low temperature, the reaction is spontaneous and < 0 and at high temperature, the reaction is spontaneous and < 0, is correct.

Hello.
When dealing with two or more elements in a fixed proportion, your answer is going to be "B.) Compound." The explanation is pretty basic when you narrow it down - think of it like the English version of a compound sentence; there are two independent clauses that have related ideas (such as this one, for example).
Let's use an example of a compound element, such as
, or Water.
This is a compound element that is composed of the two elements "Hydrogen" and "Oxygen" - for every 2 Hydrogen atoms there is one Oxygen atom.
I hope this helps!
This is a good riddle. The answer is ICE, because ice can break things, even ships like the titanic and it also makes steel weak but when the sun comes it melts away so it’s cowers away.
