The formula for a lutetium carbonate compound is Lu2(CO3)3. What would be the formula for a lutetium nitrate compound given that the charge of lutetium is the same in both compounds?

a. LuNO3
b. Lu2NO3
c. Lu(NO3)2
d. Lu2(NO3)3
e. Lu(NO3)3

Respuesta :

Answer:

E

Explanation:

From Lu2(CO3)3, we can determine the charge of the variable charge transition metal Lu has a charge of 3, as CO3 has a 2- charge (3*-2 = 6, 6/2 = 3). Then, we apply this to nitrate, which has a charge of 1-. Balance charges, reduce, and you get E.
