Answer:

b) At equilibrium, equal amounts of products and reactants are present.

Explanation:

At equilibrium , the ratio of product of concentration of products  and product of concentration of  reactants is constant .

                                             A + B ⇄ C + D

                                 [C] [ D]  / [ A ] [ B ] = Constant

So, the statement ( b )  is false .

All other statements are true .

Yuri [45]
I think the correct answer from the choices listed above is option A. A can of diet soda will float in water while a can of regular sugar soda will sink. This is due to the reason that the regular soda is more dense than the diet soda. Hope this answers the question.

A mixture initially contains A, B, and C in the following concentrations: [A] = 0.650 M, [B] = 1.35 M, and [C] = 0.300 M. The fo
dimaraw [331]

<u>Answer:</u> The value of K_c for given reaction is 0.465

<u>Explanation:</u>

We are given:

Initial concentration of A = 0.650 M

Initial concentration of B = 1.35 M

Initial concentration of C = 0.300 M

Equilibrium concentration of A = 0.550 M

Equilibrium concentration of B = 0.400 M

For the given chemical equation:

                           A+2B\rightarrow C

<u>Initial:</u>                0.65     1.35     0.30

<u>At eqllm:</u>        0.65-x   1.35-2x   0.30+x

Evaluating the value of 'x'

0.650-x=0.550\\\\x=0.100

So, equilibrium concentration of B = 1.35 - 2x = [1.35 - 2(0.100)] = 1.15 M

Equilibrium concentration of C = (0.30 + x) = (0.300 + 0.100) = 0.400 M

The expression of K_c for above equation follows:

K_c=\frac{[C]}{[A][B]^2}

Putting values in above equation, we get:

K_c=\frac{0.400}{0.650\times (1.15)^2}\\\\K_c=0.465

Hence, the value of K_c for given reaction is 0.465

How are the frequency and energy of an electromagnetic wave related? (2 points) As frequency increases, energy increases As freq
astraxan [27]

Answer:

As frequency increases, energy increases

Explanation:

The energy of electromagnetic waves increases as frequency increases. It is the wavelength that decreases when the energy of electromagnetic waves increases.

We can say a direct relationship exists between frequency and energy of electromagnetic waves.

The high energy waves in an electromagnetic spectrum are x-rays, ultraviolet rays etc. These waves also have a high frequency.

Frequency is the number of waves that passes a particular point per seconds. The more the frequency or the number of waves passing through, the more energy it is able to produce and release.
