Answer:
a) 0 Na + H204 = 0 NaOH + 102 H2
b) 4Fe + 3O2 = 2Fe2O3
c) 2NO + O2 = 2NO2
d) 2KCIO = 2KCI + O2
e) 2Ca + O2 = 2CaO
Explanation:
The number of atoms of a compound or element should be the same in both the reactant side and the product side. You can never change the subscript or remove any parts of the chemical equation, you can only add the coefficient (the number before the element/compound)
You need to multiply the subscript and coefficient to get the total number of atoms in the compound/subscript.
