An experiment was undertaken to determine the effect of different liquids upon the swelling of a vulcanized sample of natural ru

bber at room temperature. It was found that the equilibrium swelling ratio of the natural rubber in carbon tetrachloride was 5.5 and in benzene it was 4.4. Given the information below determine the following parameters.
(a) The molar mass between crosslinks, Mc for the natural rubber sample.
(b) The value of the Flory-Huggins interaction parameter, x, for natural rubber in benzene.

(The density of natural rubber=910 kg M^-3; Flory-Huggins interaction parameter x for natural rubber in carbon tetrachloride=0.290; molar volume of carbon tetrachloride=97.1 x 10^-6 m^3 mol^-1; and molar volume of benzene=89.4 x 10^-6 m^3 mol^-1.)

A proton is a subatomic particle carrying a charge equal to but opposite that of an electron
Pachacha [2.7K]

Answer:

True

Explanation:

A proton has a charge of +1, while an electron has a charge of -1. This is why a neutral atom has the same number of protons as electrons.

Neutrons have no charge, hence their name neutron which is similar to neutral.

What is meant when one says that acetic acid is a stronger acid than benzoic acid?
kozerog [31]

Its the other way around actually. Benzoic acid is stronger than acetic acid because the electron-donating inductive effect (+I) by the alkyl group on acetic acid destabilise the conjugate base of acetic acid.

hope this helps :)
