What is subshell and why do we use it if we have main shells already

Chemistry
1 answer:
kumpel [21]3 years ago
5 0
Principal shell shows the main energy level, in that there are some more energy levels. This is how the atomic structure is defined according to the Quantum Mechanical model of atom. So exactly why do subshells exist and all i don't know

Foods cook faster when placed in a pressure cooker. This is because the pressure on the surface of the water is (higher than/low
tia_tia [17]

Answer:

The pressure is higher than the atmospheric one, therefore the temperature is less.

Explanation:

When it is closed permanently, the pressure of the pot inside it increases, generating that the atoms and particles of the water are closer together, increasing their kinetic energy, if intermolecular friction and therefore the boiling point is lower, because the water reaches a boil or boil at a lower temperature.

Which statement correctly compares electric charge with electric current?
Arisa [49]

Answer:

Your answer would be D) They both require a movement of charged particles

Explanation:

In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use

Convert 1.7 Kg to cg
Kipish [7]
To answer this lets first see how much 1 kg is equal to in cg.

1 kg = 100000 cg 

Now lets multiply:-

100000 × 1.7 =  <span>170000
</span>
So, 1.7 kg = <span>170000 cg

23.5 L of h2 is stored at a pressure of 58.7 Kpa what volume would the gas take up at stp
stepan [7]

Answer:-  13.6 L

Solution:- Volume of hydrogen gas at 58.7 Kpa is given as 23.5 L. It asks to calculate the volume of hydrogen gas at STP that is standard temperature and pressure. Since the problem does not talk about the original temperature so we would assume the constant temperature. So, it is Boyle's law.

Standard pressure is 1 atm that is 101.325 Kpa.

Boyle's law equation is:

P_1V_1=P_2V_2

From given information:-

P_1 = 58.7 Kpa

V_1 = 23.5 L

P_2 = 101.325 Kpa

V_2 = ?

Let's plug in the values and solve it for final volume.

58.7Kpa*23.5L=101.325Kpa*V_2

On rearranging the equation for V_2

V_2=\frac{58.7Kpa*23.5L}{101.325Kpa}

V_2 = 13.6 L

So, the volume of hydrogen gas at STP for the given information is 13.6 L.
