For example we are going to use this unbalanced chemical reaction:
H₂ + O₂ → H₂O.
First, calculate number of atoms (hydrogens and oxygens) on left and right. There is two oxygen and two hydrogen on left and two hydrogen and one oxygen on right.
You can not change molecular formula of compound, only you can put coefficient in fron of compound to balance reaction.
Put 2 in front water to balance oxygen (now you have two oxygens on left and right). But now you have four hydrogens on right, so you must put 2 in fron hydrogen on the left.
2H₂ + O₂ → 2H₂O.
Infrared radiation
Explanation:
The type of electromagnetic waves Jeff uses to make his goggles work are the infrared radiations.
Jeff is certainly using a night vision goggle to see in the dark . It senses infrared radiations
- Infrared radiations are part of the electromagnetic spectrum.
- Every hot objects gives off infrared radiations.
- These googles have thermal imaging sensors that detects these radiations.
- Naked eyes cannot see the radiations.
- The heat emitted is a form of radiation called the infrared radiation.

The process in which the concentration of the solution is lessened by the addition of water is said to be dilution and equation of dilution relates the initial concentration and volume of stock solution with the final concentration and volume of the solution.
Formula is given by:
(1)
where,
is the initial concentration
is the initial volume
is the final concentration
is the final volume
Now,
= 0.850 M
= 4.12 L
=?
= 10.00 L
Substitute the give values in formula (1),
= 
Thus, the final concentration of the
solution =
