Which substance is made of polymers? A. marble B. protein C. salt D. steel
2 answers:
Answer: Option B) is the correct answer.
Explanation:
A polymer is defined as a molecule which has 'n' number of monomer units.
For example, is a poly ethene polymer.
Similarly, proteins are also polymers as they are made up of amino acids and contain number of repeated units just like polymers.
Thus, we can conclude that protein is made of polymers.

b. the rate of effusion of sulfur dioxide = 2.5 faster than nitrogen triiodide
<h3>Further explanation</h3>Given
T = 100 + 273 = 373 K
Required
a. the gas speedi
b. The rate of effusion comparison
Solution
a.
Average velocities of gases can be expressed as root-mean-square averages. (V rms)
R = gas constant, T = temperature, Mm = molar mass of the gas particles
From the question
R = 8,314 J / mol K
T = temperature
Mm = molar mass, kg / mol
Molar mass of Sulfur dioxide = 64 g/mol = 0.064 kg/mol
b. the effusion rates of two gases = the square root of the inverse of their molar masses:
M₁ = molar mass sulfur dioxide = 64
M₂ = molar mass nitrogen triodide = 395
the rate of effusion of sulfur dioxide = 2.5 faster than nitrogen triodide
