The ball and stick model of C subscript 2 H subscript 4 is described as Option C: Each C has 2 H's connected to it each by 1 black.
This means the same as the 3D structure image of ethylene (C2H4) and means 2 C's connected by 2 black lines.
line.
The structure of ethylene is made up of 2 carbon atoms and 4 hydrogen atoms.
The carbon atoms are located at the middle position and the hydrogen atom surrounding the carbon atoms with two hydrogen atoms connected to each carbon atom. The two black lines connecting the carbons are the double bonds.

Answer:
Laws governing gas behavior.
Explanation:
Boyle's law:
It relates the pressure and volume of an ideal gas at a constant temperature.
According to this law:
"The volume of a fixed amount of gas at constant temperature is inversely proportional to its pressure".
.
Charle's law:
It relates the volume and absolute temperature of an ideal gas at a constant pressure.
According to this law:
"The volume of a fixed amount of gas at constant pressure is directly proportional to its absolute temperature".
.
Avogadro's law:
According to this law:
equal volumes of all gases under the same conditions of temperature and pressure contain, an equal number of moles.
.
Ideal gas equation:
By combining all the above-stated gas laws, this equation is formed as shown below:
R is called universal gas constant.
It has a value of 0.0821L.atm.mol-1.K-1.
