Which compound is not correctly balanced by charge in the following reaction?
fe(no3)2 + al2(co3)3 + feco3 + aino3

a. fe(no3)2
d. aino,
b. al(co3)3
e. fire truck
c. feco3

C. FeCO₃

Balanced equation: 3Fe(NO₃)₂ + Al₂(CO₃)₃  → 3FeCO₃ + 2AI(NO₃)₃

Explanation:

To identify the compound that is not completely balanced we need to look at the number of atoms of each element.

The given equation is;

Fe(NO₃)₂ + Al₂(CO₃)₃  → FeCO₃ + AINO₃

On the reactant side; 1 iron atom, 2 nitrogen atom, 15 oxygen atoms, 2 aluminium atoms and 3 carbon atoms.On the product side: 1 iron atom, 1 nitrogen atom, 6 oxygen atoms, 1 aluminium atoms and 1 carbon atom.The equation is not balanced and the compound that is not correctly balanced is FeCO₃.Therefore, the balanced equation should be written as;

3Fe(NO₃)₂ + Al₂(CO₃)₃  → 3FeCO₃ + 2AI(NO₃)₃
