Explain Charles law
1 answer:
"Charles Law" is the relationship between "volume-temperature" (V ∝ T).
<u>Explanation</u>:
Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at for each one degree rise or fall in temperature”. Formula derived from law is as follows:
here
is volume of given mass of a gas at
,
is its volume at any temperature
. Application of Charles law is hot air balloons.

Answer : The balanced chemical equation in a acidic solution is,
The sum of the coefficients is, 17
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Rules for the balanced chemical equation in acidic solution are :
First we have to write into the two half-reactions.
Now balance the main atoms in the reaction.
Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the less number of oxygen are present.
If the hydrogen atoms are not balanced on both the sides then adding hydrogen ion at that side where the less number of hydrogen are present.
Now balance the charge.
The given chemical reaction is,
The oxidation-reduction half reaction will be :
Oxidation :
Reduction :
- First balance the main element in the reaction.
Oxidation :
Reduction :
- Now balance oxygen atom on both side.
Oxidation :
Reduction :
- Now balance hydrogen atom on both side.
Oxidation :
Reduction :
- Now balance the charge.
Oxidation :
Reduction :
The charges are not balanced. Now multiplying oxidation reaction by 3 and then adding both equation, we get the balanced redox reaction.
Oxidation :
Reduction :
The balanced chemical equation in acidic medium will be,
The sum of the coefficients = 1 + 6 + 3 + 1 + 3 + 3
The sum of the coefficients = 17
