A chemist prepares a solution of barium acetate (Ba(CH, CO*
by measuring out 60.3 umol of barium acetate into a 450 mL volumetric flask and filling the
flask to the mark with water.
Calculate the concentration in mmol/L of the chemist's barium acetate solution. Round your answer to 3 significant digits.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

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.
