2 answers:
<u>Answer:</u> The correct answer is option A.
<u>Explanation:</u>
A compound is defined as the substance in which two different elements combine in a fixed ratio. Example: etc..
An element is defined as the simplest substance having same type of atoms. Example: Carbon (C), Oxygen (O) etc..
Allotrope is defined as a property of some elements in which they are exist in different physical forms. Examples: Allotropes of carbon are graphite, diamond etc..
In a given image, the molecule is made up of two different types of elements which are hydrogen and carbon. Hence, it is termed as a compound named as ethane.
Thus, the correct answer is Option A.

Answer : The rate of effusion of sulfur dioxide gas is 52 mL/s.
Solution :
According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.
or,
..........(1)
where,
= rate of effusion of nitrogen gas =
= rate of effusion of sulfur dioxide gas = ?
= molar mass of nitrogen gas = 28 g/mole
= molar mass of sulfur dioxide gas = 64 g/mole
Now put all the given values in the above formula 1, we get:
Therefore, the rate of effusion of sulfur dioxide gas is 52 mL/s.
