How will four electrons be distributed in three empty 2p atomic orbitals?

1 answer:

8 0

B
Orbitals fill in a way that all of them first gain one electron, and then they start receiving the second electron if any are left. Thus, the three will fill with one electron each first and then the fourth will go into the first.

Explain whether changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced. Include the evidenc

PilotLPTM [1.2K]

Answer:

Reducing the amount of vinegar will reduce the amount of carbon dioxide produced because there will be fewer molecules of acetic acid to react with the baking soda and produce the carbon dioxide.

To make more carbon dioxide, you could add either more acetic acid or more sodium bicarbonate or more of both.

Mashutka [201]

Answer:

The correct answer is - adrenal medulla.

Explanation:

The adrenal medulla is the internal part of the the adrenal gland that is the controlled by the sympathetic nervous system, Adrenal medulla is part of the adrenal gland where different molecules act as the hormones.

Adrenal medulla include various hormones as secreted hormones from there. Fight or flight is also initiate by the hormones secreted from adrenal gland that are epinephrine, nor epinephrine.

Thus, the correct answer is - adrenal gland.

As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction: 2 NO2 (g) ⇋ N2

dmitriy555 [2]

Answer:

3500

Explanation:

The equilibrium constant of the reaction which has to be calculated is:-

2 NO2 (g) ⇋ N2(g) + 2 O2(g)

The given chemical equation follows:

1/2 N2 (g) + 1/2 O2 (g) ⇋ NO (g)

The equilibrium constant for the above equation is 0.004.

We need to calculate the equilibrium constant for the reverse equation of above chemical equation and also double of the above chemical equation, which is:

2NO (g) ⇋ N2 (g) + O2 (g)

The equilibrium constant for the reverse double reaction will be the reciprocal of the initial reaction.

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

The value of equilibrium constant for reverse reaction is:

$K_{eq}'=(\frac{1}{0.004})^2$ = 62500

The given chemical equation follows:

2NO2 (g) ⇋ 2NO (g) + O2 (g)

The equilibrium constant for the above equation is 0.056.

Thus, adding the both reaction gives the original reaction. So, equilibrium constant is:- 62500 x 0.056 = 3500
