<u>density</u> is a measure of mass per volume. <u>mass</u> is both a property of a physical body and a measure of its resistance to acceleration.

As with the properties of a substance, the changes that substances undergo can be classified as either physical or chemical. During physical changes a substance changes its physical appearance, but not its composition. The evaporation of water is a physical change.
(I searched that up but here’s an explanation with my own words that you can use):
Change in matter can be classified as a physical change as well as a chemical change due to the properties of substance. A physical change changes substance within its appearance but not its composition. For an example: The evaporation of water is a physical change.
There you go hopefully that helped
Stronger intermolecular forces = higher boiling point
The stronger the intermolecular forces, the harder the molecules are to pull/break apart, which means a higher boiling point.
Answer:
n = 3
l = 1
ml = +1
ms = +1/2
Es paramagnético
Explanation:
Siguiendo las reglas de llenado de orbitales, los 17 electrones del cloro se llenan así:
1S = <u>⇅</u>
2S = <u>⇅</u>
2P = <u>⇅</u> <u>⇅</u> <u>⇅</u>
3S = <u>⇅</u>
3P = <u>⇅</u> <u>⇅</u> <u>↑</u>
<u />
El número cuántico principal n, es el nivel energético donde se encuentra este electrón:
n = 3 (Porque está en el orbital 3P
El número cuántico secundario, l, para el orbital 3P es = 1:
l = 1
El número cuántico magnético, ml, es determinado por la posición del electrón. Como está en el tercer orbital 3P:
ml = +1
Y el número cuántico de spin, ms (↑ = +1/2; ↓ = -1/2)=
ms = +1/2
Dado que el último electrón se encuentra desapareado, el cloro es paramagnético dado que el espín de el último electrón no tiene su electrón complementario haciendo que este compuesto pueda interactuar con un campo magnético.
