As we know valency of Hydrogen
why we write H2 & valency of chlorine is 1 then why cl2
why
plz balance this
CO₂ + H₂O
- C6H12O6 + O₂ + H₂O
My Answer is
6 C02, +7H20
-----→ + 602 + H ₂ O
But Answer on Book is
6 co2 +12H₂O→
C6 H12O6 +60₂ + 6H₂O

We write hydrogen as H but during any reaction hydrogen reacts as a molecule. The molecular formula of hydrogen is .
Same thing happens with Chlorine. The atomic formula of Chlorine is Cl but the molecule which takes part in reaction is .
Left side :
C = 1 × 6
H = 2 × 12
O = ( 2 × 6 ) + 12
Right side :
C = 6
H = 12 + ( 6 × 2 )
O = ( 2 × 6 ) + ( 6 × 2 )
- Atom - It is the smallest unit of a matter that forms elements.
- Molecule - It is the a group of atoms and the smallest unit that can take part in any chemical reaction.
- We need to balance a chemical equation because of the "Law of Conservation of Mass".
This law states that matter can neither be destroyed or created in a chemical reaction.
