Because there is only one stable ionic compound made up of potassium and chlorine, and that is KCl. So calling is "mono chloride" or similar would be redundant assuming you understand basic chemistry (i.e. knowing oxidation numbers of K is +1 and Cl is -1). When compounds can exist in multiple forms in nature like CO and CO2 you will preferably indicate it through the nomenclature, calling one a monoxide and the other a dioxide.
Answer b) a to c would be considered one wavelength.

Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
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.
