# Balance the following equation stepwise.

H_{2}S_{2}O_{7}(l) + H_{2}O(l) → H_{2}SO_{4}(l)

Answer :

** Balanced equation:** H

_{2}S

_{2}O

_{7}+ H

_{2}O → 2H

_{2}SO

_{4}

Explanation:

⇒ Step 1: Write the given unbalance equation

H_{2}S_{2}O_{7} + H_{2}O(l) H_{2}SO_{4}(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:

H_{2}S_{2}O_{7} + H_{2}O → 2H_{2}SO_{4}
