Balance the following equation stepwise.

H2S2O7(l) + H2O(l) → H2SO4(l)

Balanced equation: H2S2O7 + H2O → 2H2SO4


Explanation:


⇒ Step 1: Write the given unbalance equation


H2S2O7 + H2O(l) H2SO4(l)


⇒ Step 2: Compare the number of atoms of reactants with the number of atoms of products.



⇒ Step 3: Now, if we multiply 2 in the products, we will get the equal number of atoms as reactants.



⇒ Write down the final balanced equation:


H2S2O7 + H2O → 2H2SO4
