Given question is incomplete. The complete question is as follows.

n-butane and isobutane are in equilibrium at 25 degrees centigrade.

        n-butane(g) \rightleftharpoons isobutane(g)

A one liter flask with the two species at equilibrium contains 0.170 mole isobutane and 0.0680 mole n-butane. Then the concentration of n-butane is increase by 0.200 moles. (0.200 mole n-butane is added.) What is the new equilibrium concentration for isobutane.

Explanation:

As the given reaction is as follows.

            n-butane(g) \rightleftharpoons isobutane(g)

Initial:        x                               0

Equilbm:  x - 0.17                     0.17

It is given that equilibrium concentration of n-butane is 0.068 M.

So,           x - 0.17 = 0.0680

                 x = 0.238

Therefore, the initial concentration is 0.238.

Here,

          K_{c} = \frac{[isobutane]}{[n-butane]}

                    = \frac{0.170}{0.068}

                    = 2.5

When 0.2 mol of n-butane is added. Hence, total moles will be as follows.

       Total mole = (0.238 + 0.2)

                          = 0.438 mol

Hence, for 1 L volume the ICE table will be as follows.

           n-butane(g) \rightleftharpoons isobutane(g)

Initial:    0.438                        0

Equilbm:  0.438 - x                x

                   K_{c} = \frac{x}{0.438 - x}

                      2.5 = \frac{x}{0.438 - x}

                    1.095 - 2.5x = x

                             x = \frac{1.095}{3.5}

                                = 0.3128 M

Thus, we can conclude that the equilibrium concentration is 0.3128 M.

Acetone is a three-carbon aldehyde. True/False.
stiv31 [10]

Answer: acetone is a ketone and not an aldehyde. Therefore it's false

Explanation:

Acetone is of structure CH3-CO-CH3

which makes it a ketone.

Both aldehyde and ketone have a carbonyl group but there is difference between aldehyde and ketone.

Aldehydes have a general formula R-CHO

where R is a methyl group including H atom, and CHO is the functional group.

While

Ketone have the general formula R-CO-Ri

where R and Ri are methyl groups excluding H atom, and CO is the functional group.

Hint: ketones usually end with the suffix "one" as in acetone.

When heat energy is removed, two changes are observed:
harkovskaia [24]

Answer: Option (A) is the correct answer.

Explanation:

Condensation is defined as the process in which vapors or gaseous phase changes into liquid phase.

Freezing is the process in which liquid phase changes into solid phase.

Evaporation is the process in which liquid phase changes into vapors or gaseous phase.

Melting is the process in which solid phase changes into liquid phase.

Therefore, we can conclude that names for given phase changes A and B is that A is condensation and B is freezing.
