Compounds containing unpaired electrons are paramagnetic in nature, while compounds containing no unpaired electrons are diamagnetic in nature.

Attached is the molecular orbital diagram of S2 molecule. For the MOT diagram it can be seen that S2 molecule has two unpair electron in two π* orbital. Due to this, it is paramagnetic in nature.

In contrast to this, Li2, C2 and Cl2 have no unpaired electrons. Hence they are diamagnetic in nature.

What is keq for the reaction 2so2(g) + o2(g) 2so3(g)? apex?

Dennis_Churaev [7]

The keg for the reaction
2 SO2(g) + O2(g) → 2 SO3(g) is

Keg = [SO3]^2/ {(SO2)^2 ( O2)}

Keg (equilibrium constant) is the ratio of of equilibrium concentration of the product raised to the power of their stoichiometric coefficient to the equilibrium concentration of the reactant raised to the power of their stoichiometric coefficient.

What is the value for the reaction: N2(g) + 2 O2(g) --> N2O4(g) in terms of K values from the reactions:

Valentin [98]

Answer : The correct expression will be:

$K=(K_1)^2\times K_2$

Explanation :

The chemical reactions are :

(1) $\frac{1}{2}N_2(g)+\frac{1}{2}O_2(g)\rightleftharpoons NO(g)$ $K_1$

(2) $2NO(g)+O_2(g)\rightleftharpoons N_2O_4(g)$ $K_2$

The final chemical reaction is :

$N_2(g)+2O_2(g)\rightleftharpoons N_2O_4$ $K=?$

Now we have to calculate the value of $K$ for the final reaction.

Now equation 1 is multiply by 2 and then add both the reaction we get the value of 'K'.

If the equation is multiplied by a factor of '2', the equilibrium constant will be the square of the equilibrium constant of initial reaction.

If the two equations are added then equilibrium constant will be multiplied.

Thus, the value of 'K' will be:

$K=(K_1)^2\times K_2$

When do replicated chromosomes are aligned in the center

Art [367]

Answer:

During Metaphase

Explanation:

During Metaphase the cell chromosome align themselves in the middle of the cell.This occur due to a cellular process called "Tug of War".

The chromosome which have been replicated and joined at the central point called centromere are called sister chromatids

Prior to metaphase , Kinetochore type of protein are formed around the centromere. Long protein filament called kinetochore are extended from poles to other end of the cell attached to kinetochore.

Therse is important checkpoint in the middle of mitosis called metaphase.

At this point cell ensure that , it is ready to divide or not.

Once the cell ensure that everything is ready to divide. Only after then , yhe cell enters the fourth phase called anaphase.

Do you think that the human being is the center of the universe?

Andrej [43]

I think that the sun is the center of the universe, not a human being. Everything revolves around the sun, not someone. U know when to sleep, when the time is, and when to wake up based on the sun. All the planets revolve around it. This is why I think the sun is the center of the universe, not a human being.
