What is the correct formula for the compound iron(lll) carbonate? (a) feco3 (b) fe3co3 (c) fe2co3 (d) fe2(co3)3 (e)fe3(co3)2

The correct answer is Option d.

Explanation:

We are given an ionic compound named as iron (III) carbonate.

Iron is the 26th element of periodic table having electronic configuration of .

This element will loose 3 electrons to form ion.

Carbonate ion is a polyatomic ion having chemical formula of

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is

Thus, the correct answer is Option d.

the ratio of the conjugate base to the acid required to attain the desired ph.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
