Answer:

-Determination - in this stage, people have make commitment to change the bad habit as soon as possible. it is stage of planning.

Explanation:

There are six stages of change that have a unique role in changing one's behavior. The stages are:

-Pre-contemplation - in this stage people are more aware of this bad habit but at the same time they are not considering as a problem

- contemplation - At this stage, people are more serious about their bad habit and now are thinking of changing

-Determination - in this stage, people have made a commitment to change the bad habit as soon as possible. it is stage of planning.

- Action - at this stage of change people are taking a serious step toward changing their behavior

- Maintenance - in this stage people are avoiding all those criteria and source through which there is a chance to return back to bad habits

-Relapse - at this stage people do resumption of old behavior

nekit [7.7K]

<u>Answer:</u> The relation between the forward and reverse reaction is $K_f=\frac{1}{K_r}$

<u>Explanation:</u>

For the given chemical equation:

$2NH_3(g)\rightleftharpoons N_2 (g)+3H_2(g)$

The expression of equilibrium constant for above equation follows:

$K_f=\frac{[N_2][H_2]^3}{[NH_3]^2}$ .......(1)

The reverse equation follows:

$N_2 (g)+3H_2(g)\rightleftharpoons 2NH_3(g)$

The expression of equilibrium constant for above equation follows:

$K_r=\frac{[NH_3]^2}{[N_2][H_2]^3}$ .......(2)

Relation expression 1 and expression 2, we get:

$K_f=\frac{1}{K_r}$

Hence, the relation between the forward and reverse reaction is $K_f=\frac{1}{K_r}$

Selenium (Se) has 30 protons and 20 neutrons in each atom, therefore its atomic

allochka39001 [22]

Answer:

30, 50

Explanation:

Hello,

In this since an element's atomic number is equal to the number of protons in its atom, we can infer that selenium's atomic number is 30. Moreover, due to the fact the the neutrons are equal to the atomic mass minus the atomic number or the number of protons, by knowing the number of neutrons we compute the atomic as follows:

$neutrons=mass-protons\\\\mass=neutrons+protons\\\\mass=30+20\\\\mass=50a.m.u$

Thus, answer is 30, 50.

Best regards.

When the temperature of the air is 25°C, the velocity of a sound wave traveling through the air is approximately

Vitek1552 [10]

Answer ; The correct answer is : 346 m/s .

Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .

Speed of sounds depends on factors like medium , density , temperature etc .

Effect of Temperature on speed of sounds :

When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .

The speed of sounds at 0⁰C is 331 $\frac{m}{s}$
