Answer: Absolute dating can be used to determine the exact age of the rock, and relative dating is used to compare the ages of rocks.
The determination of the exact age of the rock is done by using the properties of atoms. Radioactive atoms decay with specific half-life times, so the half-life of the radioactive atoms along with the measurement of the amounts of materials in the parent and the daughter rocks permits to determine the age of the rock.
The given question is based on the concept of conversion factor
1 KL = 10³ L, 1cL = 10⁻³ L, 1dL = 10⁻² L, 1 nL = 10⁻⁹ L
<h3>What is Conversion factor ?</h3>
A conversion factor is an expression for the relationship between units that is used to change the units of a measured quantity without changing the value.
A conversion ratio (or unit factor) always equals one (1), where the numerator and the denominator have the same value expressed in different units.
Hence, The complete filled table is given as follows ;
1 KL = 10³ L,
1cL = 10⁻³ L,
1dL = 10⁻² L,
1 nL = 10⁻⁹ L
Where,
- KL is Kilolitre
- cL is centilitre
- dL is decilitre
- nL is nanolitre

No graphs attached but we will solve it via assumption and using facts about reaction at equilibrium
So
According to Le cha tteler's principle
- Any change to be done on reaction at equilibrium position changes the speed of reaction to happen
So
If we add catalyst as its general behaviour is to increase reaction speed ,
- Higher the speed, higher the reaction progress
- Higher the kE higher the reaction progress
- Higher the PE higher the reaction progress
The graph must be a straight line
The answer is C, Air is the least dense, water has be before oil because of polarity reasons and has a low density too
A typical human hair is about 1 million carbon-12 atoms JUST IN WIDTH.
