When determining the concentration of an acid solution, the titrant would usually be put in the burette while the analyte would be in the conical flask.
The titrant is usually a known solution while the analyte would be the unknown solution.
In order to determine the concentration of a solution of hydrofluoric acid, the acid would need to be titrated against a suitable base of known concentration using a suitable indicator to indicate the endpoint of the neutralization reaction.
Thereafter, the volume of the titrant used would be recorded and used to find the concentration of the acid (the analyte).
Thus, since the base would be known, it would be the one in the burette while the hydrofluoric acid would be the one in the conical flask.

I think that it is half are required to react with 40 g of HF.
Observations in the scientific method lead to questions which need answers. The hypothesis is a testable argument presented in scientific method to address a question. Experiments (often with controls and variables) are formulated in the experimental method for evaluating theories. Hope this helps ✨
What is Solidification?
The process by which liquid metals turn into tiny solid particles at the phase boundary temperature is known as solidification or freezing.
How does solidification occur?
Solidification occurs when a liquid's temperature is reduced below its freezing point. Although the freezing point and melting point of the majority of materials are the same temperatures, this is not always the case and the words freezing point and melting point are not synonymous.
When a liquid turns into a solid, the process is always exothermic, which means heat is released.
Based on casting technology, solidification is a key component of several other processes, such as crystal growth, welding, surface alloying, the manufacturing of ingots, and the purification and refinement of raw materials. It is a crucial step in the technology of metals, as well as ceramics and polymers.

Answer: Option (d) is the correct answer.
Explanation:
It is given that molecular formula is . Now, we will calculate the degree of unsaturation as follows.
Degree of unsaturation =
=
= 9 - 8 + 1
= 2
As the degree of unsaturation comes out to be 2. It means that this compound will contain one ring and one double bond.
Yes, this compound could be an alkyne as for alkyne D.B.E = 2.
But this compound cannot be a cycloalkane because for a cycloalkane D.B.E = 1 which is due to the ring only.
Thus, we can conclude that it is a cycloalkane is not a structural possibility for this hydrocarbon.
