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

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

Fe(NO₃)₂ + Al₂(CO₃)₃  → FeCO₃ + AINO₃

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

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

the answer is d. 74.02
