The principal energy level at n=3 contains s,p,d orbitals in their valence shell.

Option(b);

<u>Explanation:</u>

"Principal energy level" is used to locate the no of electrons in each orbital to its atomic nucleus. These energy levels are denoted by the "principal quantum number" n.

There are four energy level of orbits available in this system. And the following shows different level of orbits and the no of electrons for each value of n

At n=1, Orbital name=S, No of electrons=1
At n=2, Orbital name=S, P, No of electrons=4
At n=3, Orbital name=S, P, D, No of electrons=9
At n=4, Orbital name=S, P, D, F, No of electrons=16

Find the volume of 20g of H₂ at STP<br><br>

ANEK [815]

Answer:224

Explanation:

We should answer it with Stoichiometry

We say: 20 g H2× (1 mol/ 2g)× ( 22.4 lit/ 1 mol) = 224

Means: we have 20 grams and every 2g H2, equals to 1 mol of it and every 1 mol of H2, equals to 22.4 lit( because of STP)

hope you got this:)

How does removing thermal energy from liquid water affect the molecules in the water?

galina1969 [7]

Answer:

For deposition to happen, thermal energy must be removed from the gas. ... As water vapor loses thermal energy, it changes into solid frost. States of Water. Water is the only substance that exists naturally as a solid, a liquid, and a gas within Earth's temperature range.

An open "empty" 2 L plastic pop container, which has an actual inside volume of 2.05 L, is removed from a refrigerator at 5 °C a

Pani-rosa [81]

2.168 L of air will leave the container as it warms

<h3>Further explanation</h3>

Given

V₁=2.05 L

T₁ = 5 + 273 = 278 K

T₂ = 21 + 273 = 294 K

Required

Volume of air

Solution

Charles's Law

When the gas pressure is kept constant, the gas volume is proportional to the temperature

$\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

Input the value :

V₂=(V₁.T₂)/T₁

V₂=(2.05 x 294)/278

V₂=2.168 L
