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.

B. using a spatula
C. fractional destilations
If you’re referring to he red stuff- the liquids can be ethanol, toluene, kerosene, or isoamyl acetate. They’re transparent so they’re made more visible with red dye. (So I’d guess the answer is ethanol)
I found this in the Wikipedia article ‘Alcohol thermometer’
Answer: 6.0 g of silicon has more atoms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
a)
1 mole of Si contains = atoms
0.21 moles of Si contains = atoms
b)
1 mole of Fe contains = atoms
0.11 moles of Fe contains = atoms
Thus 6.0 g of silicon has more atoms
