All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers.
Answer:
d = 0.743 g/cm³
Explanation:
Given data:
Mass of cylinder = 65.34 g
Height = 15.60 cm
Radius = 1.34 cm
Density of cylinder = ?
Solution:
Volume of cylinder:
V = πr²h (π = 22/7)
V = 88 cm³
Density of cylinder:
d = m/v
d = 65.34 g / 88 cm³
d = 0.743 g/cm³
Well, after 1 half life, depending on whatever the amount is, 50% of the original content and or remaining content will undergo decay, as it is unstable.
Original content - 200g
1 half life - 100 g
2 half life - 50 g
3 half life - 25 g
The correct solution would be D. 25 g.
Answer : The correct option is, (b) +115 J/mol.K
Explanation :
Formula used :
where,
= change in entropy
= change in enthalpy of vaporization = 40.5 kJ/mol
= boiling point temperature = 352 K
Now put all the given values in the above formula, we get:
Therefore, the standard entropy of vaporization of ethanol at its boiling point is +115 J/mol.K
