Chemistry How to Balance Chemical Equations
Answer:
Today we are going to balance reactions in chemistry.
Let us consider the following reaction in chemistry.
Na+ Cl₂→NaCl
TO balance the reaction in chemistry ,follow the following steps.
Step-1:
Write the equation like this and count atoms from both sides.
Na+ Cl₂→NaCl
Reatants Products
Na → 1 Na → 1
Cl → 2 Cl →1
Step-2:
Balance sodium first.The number of sodium of atoms is already balanced.
Na+ Cl₂→NaCl
Reatants Products
Na → 1 Na → 1
Cl → 2 Cl →1
Step-3:
Now balance chlorine.Then update the number of sodium.
Na+ Cl₂→2NaCl
Reatants Products
Na → 1 Na → 1×2=2
Cl → 2 Cl →1×2=2
Step-4:
Now balance sodium again.
Step-4:
Now balance sodium again.
2Na+ Cl₂→2NaCl
Reatants Products
Na → 1×2=2 Na → 1×2=2
Cl → 2 Cl →1×2=2
Now change arrow sign→to equal sign (=).
2Na+ Cl₂=2NaCl
The above equation is balanced .
Notice that both sides of the equation have 2Na and 2Cl.
