A certain liquid X has a normal freezing point of −1.30°C and a freezing point depression constant =Kf5.19·°C·kgmol−1. Calculate the freezing point of a solution made of 34.5g of iron(III) chloride (FeCl3) dissolved in 850.g of X. Round your answer to 3 significant digits.

°C

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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.
