Answer:
T<span>he gaseous product of this reaction is water (Option-A).
Explanation:
This is a very interesting experiment. Take sugar in a beaker and add concentrated Sulfuric Acid into it. After a while an exothermic reaction will initiate with the formation of Carbon Black and Water vapors. You will observe the formation of hard and hot stem like body which is completely Black. This blackness is due to C and the water vapors will eliminate in the form of steam as the temperature has arised.</span>
Two or more compounds that have same molecular formula but differ in the arrangement of atoms in molecule and thus posses different properties are known as isomers.
The molecular formula of pentane is substituting one hydrogen from pentane with bromine results in the formation of monobromo derivatives of pentane having molecular formula, .
The structure of monobromo derivatives of pentane that is 1-bromopentane, 2-bromopentane, and 3-bromopentane and having molecular formula, is shown in the image.
The other two arrangements of monobromo derivatives of pentane that is 2-bromo-2-methylbutane and 2-bromo-3-methylbutane is shown in the image.
There are different structures of monobromo derivatives of pentane having molecular formula, which contain a 4-carbon chain are 1- bromo-2-methylbutane and 1-bromo-3-methylbutane shown in the image.
Answer:
Pb(NO3)2 + 2NaCl = 2NaNO3 + PbCl2
Explanation:
The given data is as follows.
n = 1 mol,
Q = 1500 J, R = 8.314 J/mol k
(a)
And, according to the first law of thermodynamics
And, in an isothermal process the change in internal energy of the gas is zero.
Hence, 0 = Q - W
or, W = Q
Expression for work done in an isothermal process is as follows.
W =
As W = Q, Hence expression for Q will also be given as follows.
Q =
Now,
[/tex]\Delta S = nR ln \frac{V_{f}}{V_{i}}[/tex]
=
= nR ln 2
=
= 5.76 J/K
Therefore, change in entropy is 5.76 J/K.
(b) As, Q =
=
= nRT ln 2
T =
=
= 260.4 K
Therefore, temperature of the gas is 260.4 K.
Make a ratio of the number of moles and do the calculations. Do you get it?
