Did you make a typo on 2. Is that supposed to be dinitrogen pentoxide. 4 isn't right. CuCl2 is copper(II) chloride.
yes i made a typo for 2
Dinitrogen pentoxide is the correct name for N2O5.
I would count MgCl2 as correct if a student named it magnesium dichloride but the purists would count that wrong. Because Mg has only +2 valence; therefore, MgCl2 is the only chloride of Mg and the di for dichloride is not necessary. Magnesium chloride is the correct name for MgCl2.
