Id guess its NF3 as...
(+)NaCl(-) = 0 is linear and the charges cancel so its no polar
(+3)AlF3(-3) = 0 the charges cancel so its non polar
Br2 is a diatomic element and elements don't have charges so its non polar
NF3 the N has a lone pair of electrons (:) and so it will repel the fluorine's as fluorine is the most electronegative element there is an unbalance in the charges so NF3 is polar
hope that helps
The conductivity would decrease because the concentration of ions decreases.
As barium hydroxide, a solution is added to sulphuric acid, the Barium ions replace the hydrogen ions to form a precipitate. An insoluble solid doesn't contribute ions and as such the forming of the solid barium hydroxide would mean a decrease in the concentration of the ions.
Answer:
2.4E-4
Explanation:
Hello,
By applying the following mass-mole relationship, the concentration could be computed as follows (assuming molarity as long as it isn't specified), since in the silver carbonate two silver molecules are present:
Best regards.
True, because matter is anything that occupies space and has mass.
