¡Hola!
1. En este caso, dado que la molaridad de una solution es calculada por medio de la siguiente ecuación:
Es posible calcular la molaridad de 50 gramos de hidróxido de potasio primero calculando las moles en dicha masa por medio de la masa molar:
Luego, dado el volumen de la solución, podemos calcular la molaridad:
2. En este segundo ejercicio, procedemos de la misma manera, pues primero calculamos las moles de nitrato de potasio:
Luego, calculamos la molaridad justo como se hizo anteriormente:
Best regards!
The answer is so you do not overheat
Answer:
c
Explanation:
The number of jobs in renewable energy worldwide increased in 2020, despite the huge economic disruptions caused by the pandemic, with the growing industry holding up better than fossil fuels. so which means reasourses are limited because of the pandemic and prises on thing rising.
Explanation:
It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.
n = l + 1
where, n = principle quantum number
l = azimuthal quantum number
Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l is 0 for s, 1 for p, 2 for d, 3 for f, and so on.
Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.
- Electronic configuration of Li is
. So here, n = 2, l = 0, m = 0 and s = ± 
.
- Electronic configuration of
is ![[Ar]3d^{10}4s^{2}4p^{6} ](https://tex.z-dn.net/?f=%5BAr%5D3d%5E%7B10%7D4s%5E%7B2%7D4p%5E%7B6%7D%0A)
. So here, n = 4, l = 1, m = -1, 0, +1, and s = ± .
- Electronic configuration of
is ![[Kr]4d^{10}5s^{2}5p^{6}](https://tex.z-dn.net/?f=%5BKr%5D4d%5E%7B10%7D5s%5E%7B2%7D5p%5E%7B6%7D)
. So here, n = 5, l = 1, m = -1, 0, +1, and s = ± .
- Electronic configuration of B is
. So here, n = 2, l = 1, m = -1, 0, +1, and s = ± .
