Answer: Option (D) is the correct answer.
Explanation:
A polymer is a large molecule which contains repeating units.
A polymer forms long chain of atoms which are not necessarily arranged in a ring structure. There are not only double bonds between all the carbon atoms, as there can be single bonds or triple bonds between the atoms of a polymer.
A polymer does not contain many different type of molecules as there are many repeating units and not many molecules in a polymer.
A polymer is made of large molecules with repeating units.
Thus, we can conclude that option (D) is the correct answer.

Answer:
They are the same.
Reaction B has a higher activation energy
Reaction A will most likely proceed faster
Answer:
λ = 1.5 m
Explanation:
Given data:
Speed of wave = 1500 m/s
Frequency of sound = 1000 Hz
Wavelength of sound = ?
Solution:
Speed of wave = frequency × wavelength
by putting values,
1500 m/s = 1000 Hz × λ
λ = 1500 m/s / 1000 s⁻¹ (Hz = s⁻¹
)
λ = 1.5 m
