Question

How to balance reactions of metals with oxygen (method)?

Answer 1

HERE IS THE ANSWER FOR YOUR QUESTION;

◆◆Just try to balance by changing coefficients◆◆

◆◆The method is TRY AND ERROR◆◆

◆For Example◆

Fe(S)+02(G) Gives Fe2O3 (S).

HOPE it helps

Answer 2

if u react any metal with O2 then u will get a metal oxide . then the reaction may be balanced or maybe nt
eg- Zn +O2 =ZnO(here the equation is nt balanced)
Zinc = 1 after reaction Zinc=1
Oxygen =2 After reaction oxygen = 1
2Zn +O2 = 2ZnO
So we add 2 to ZnO hence balancing O2 but then Zn is not balanced so we add 2 to Zn before reaction .
hope it helps...
