who do i write a balance equation for the following two reactions?
Iron metal and chlorine gas react to form solid iron(III) chloride.
Solid aluminum carbonate decomposes to form solid aluminum oxide and carbon dioxide gas.

You have to know the reactant formulas and product formulas. Once you do that, you have to supply enough product to form the reactants. You have to wind up with an answer without fractions.
That's the science, the rest is practice, practice....
For your answers
Fe(s) + Cl2 (g) -> FeCl3
the Fe is OK, but the Cl isn't. If the Cl2 is tripled, I will have 2(Cl3) on the other side, which is OK, but then I need 2 Fe, which is fine. Then
2Fe + 3 Cl2 -> 2 FeCl3
Al2(CO3)3 (s) -> Al2O3(s) + CO2 (g)
Check out the balance: Al is OK, 3C on one side, but only one on the other, so the CO2 has to be tripled. Now check out the Oxygen, its OK. SO
Al2(CO3)3 -> Al2O3 + 3 CO2

Are you particular it really is nice...i in simple terms finished getting to be conscious of balancing equations and the elements could all be on a similar area...you cant have chlorine on the product and under no circumstances on the reactant..it really is what i discovered yet I definitely have a shitty instructor so i dunno...

2Fe(s) + 3Cl2(g) ===> 2FeCl3(s)
Al2(CO3)3(s) ===> Al2O3(s) + 3CO2(g)
