If CO2 is not removed by boiling the solution after the addition of HCl, how will this affect the amount of NaOH required to reach the titration endpoint

See explanation

Explanation:

CO2 reacts with water to form carbonic acid as follows;

CO2(g) + H2O(l) > H2CO3(aq)

This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.

Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
