Question

What is the coefficient of iron(lll) carbonate?

Fe(NO3)3 + (NH4)2CO3
? Fe2(CO3)3 + NH4NO3

Answer 1

As provided, this seems like a trick question. When the full equation is balanced, iron(III) carbonate does not have a coefficient (well, it technically has a coefficient of one).

The balanced equation would be 2Fe(NO3)3 + 3(NH4)2CO3 → Fe2(CO3)3 + 6NH4NO3.
