Given information:
2Na + 2H2O → 2NaOH + H2
To determine:
If the above equation is balanced
Explanation:
For an equation to be balanced the number of atoms on the reactants must be equal to the number of atoms on the products
For the given reaction:
Reactants Products
Na = 2 atoms Na = 2 atoms
H = 4 atoms H = 4 atoms
O = 2 atoms O = 2 atoms
Ans: Since there are equal number of Na, H and O atoms on the reactant and product side, the equation is balanced.
