The element of the group 17 that is most active non metal is fluorine.
The group 17 of the periodic table contains bromine(Br), iodine(I), Chlorine(Cl) and fluorine(F).
Among all the elements of the group 17. Fluorine is the smallest in size.
Because of the small size of fluorine it has the highest electronegativity in group 17.
This high electronegativity makes it a very active non metal. It provides a very high oxidizing power and low dissociation energy to the fluorine atom.
Also because of the very small size the source of attraction between the nucleus and the electrons is very high in floor in atom.
It reacts readily to form oxides and hydroxides.
So, we can conclude here that fluorine is the most active non metal of group 17.

The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.
Mathematically;
The dilution factor is given by the formula;
Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution
Final volume of the now diluted solution = 100.0 ml
Initial volume of more concentrated solution = 10.00 ml
Dilution factor = 100.0 ml/10.00 ml
Dilution factor = 10

Answer:
C2H5OH(l) +3O2(g) → 2CO2(g) + 2H2O(l)
it is combustion reaction and heat is also produced.
Explanation:
This is oxidation reduction reaction which is also called redox reaction.
C2H5OH is reducing agent while O2 is oxidizing agent.
Chemical equation:
C2H5OH + O2 → CO2 + H2O
Now we will balance the equation. In given chemical equation two carbon atoms on the left side and one carbon atom on the right side. While six hydrogen atoms are present on the left and just two hydrogen on right side. We will write coefficient two with carbon dioxide and and three with water molecules.
C2H5OH + O2 → 2CO2 + 3H2O
now we will balance the oxygen atoms. we can see there are three oxygen atoms on the left and seven on right side. we will write coefficient three with oxygen on left and equation becomes balance.
C2H5OH + 3O2 → 2CO2 + 3H2O
Complete chemical equation with physical states:
C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
First, determine the amount of vinegar in grams by multiplying the volume by the density. That is,
mass = (355 ml) x (1.01 g/mL) = 358.55 g
Then, multiply the calculated mass above by the decimal equivalent of the given percentage above.
amount of acetic acid = (358.55 g)(0.0602) = 21.58 g
