which of the following equations are balanced?

a) 2h2 + o2 → 2h2o
b) 2s + 3o2 → 2so3
c) li + cl2 → licl
d) 2k + 2h2o → h2 + 2koh
e) 2fe + cu(no3)2 → 2cu + fe(no3)2

#a.2H2 + O2 → 2H2O

#b. 2S + 3O2 → 2SO3

#d. 2K + 2H2O → H2 + 2KOH

Explanation:A balanced chemical equation is one that has equal number of atoms of each element on both sides of the equation.

In this case;

2H2 + O2 → 2H2O - is balanced since it has, 4 hydrogen atoms and 2 oxygen atoms on either sides of the equation.2S + 3O2 → 2SO3, is balanced. It has 2 sulfur atoms and 6 oxygen atoms on both side of the equation.2K + 2H2O → H2 + 2KOH, is balanced , 2 potassium atoms, 4 hydrogen atoms and 2 oxygen atoms on both side of the equation.On the other hand, the equations that are not balanced include;Li + Cl2 → LiCl2Fe + Cu(NO3)2 → 2Cu + Fe(NO3)2

This is because the number of atoms of each element is not equal on both side of the equation/

Sorry i dont understand the question can you rephase it?
