Here's what I get.
Explanation:
The isotopic symbol for an atom is
The atomic number (Z) is the number of protons (p) in the nucleus.
In a neutral atom, the number of electrons (e) equals the number of protons. n = e
The mass number (A) is the number of protons plus the number of neutrons (n).
A = p + n or
n = A - p
(a)
p = 5
e = 5
n = 10 - 5 = 5
(b)
p = 18
e = 18
n = 36 - 18 = 18
(c)
p = 38
e = 38
n = 85 - 38 = 47
(d)
p = 5
e = 6
n = 11 - 6 = 5

Answer:
The pressure is
Explanation:
From the question we are told that
The mass of the carbon monoxide is
The temperature at which takes place
The volume of the sealed vessel is
Generally the ideal gas law is mathematically represented as
Where R is the gas constant with value
n is the number of moles of carbon monoxide which is mathematically evaluated as
where is the molar mass of carbon monoxide which is a constant with value
So
Now Making P the subject we have

Explanation:
¡Hola!
En este caso, dada la información para estos problemas, procedemos de la siguiente manera, basado en las leyes de los gases ideales:
1. Una masa de aire ocupa un volumen de 5 litros a una temperatura de 120 °C Cual será el nuevo volumen si la temperatura se reduce a la mitad:
Aqui, utilizamos la ley de Charles, asegurándonos que la temperatura está en Kelvin:
2. Un gas ideal ocupa un volumen de 4000 ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante?
Aquí, utilizamos la ley de Boyle, dado que la temperatura se mantiene constante, calculando el volumen, ya que lo que se da es la presión final:
3. Un gas ocupa un volumen de 200 litros a 95°C y 782 mmHg Cual será el volumen ocupado por dicho gas a 65°C y 815 mmHg:
Aquí, utilizamos la ley combinada de los gases ideales, asegurándonos que las temperaturas están en Kelvin:
