All alcohols are polar.
True
The answer is (1). The electrons transfer form one reactant to another means that there is the change of valence. For other choices, the valence of reactant does not change.
Answer:
The correct answer is option e.
Explanation:
The formula used for root mean square speed is:
where,
= root mean square speed
k = Boltzmann’s constant =
T = temperature
M = Molar mass
= Avogadro’s number = 
Root mean square speed of carbon dioxide molecule:

Temperature of the mixture = T =?
Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol
T = 533.87 K
Root mean square speed of nitrogen molecule:

Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol

689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
