<u>Answer:</u> The solubility of ethylene gas in water is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= molar solubility of ethylene gas = ?
= partial pressure of ethylene gas = 0.684 atm
Putting values in above equation, we get:
Converting this into grams per liter, by multiplying with the molar mass of ethylene:
Molar mass of ethylene gas = 28 g/mol
So,
Hence, the solubility of ethylene gas in water is
Answer:
C) H⁺
Explanation:
When we are balancing the reaction<em> in an acid medium</em>, hydrogen is balanced using the <u>H⁺</u> species. This is most likely the intended answer of your question.
When the reaction takes place not in an acid medium, but in <em>an alkaline one</em>, then hydrogen is present as the OH⁻ species. However this option is not given in your question.
Thus the answer is option C).
Hello!
Plus, do this is more then one answer?
Or I just have to pick three?
★ It is filled with air.
★ It takes up space.
★ It is made up of atoms.
Hope It Helped! :)

Answer:
Explanation:
Dado que:
masa de oxígeno gaseoso = 100 g
presión = 1 atm
temperatura = 273 K
(a)
número de moles de oxígeno contenidos en el matraz = masa de oxígeno / masa molar de oxígeno
= 100 g / 16 gmol⁻¹
= 6.25 moles
(b) El número de moléculas de oxígeno es el siguiente:
Dado que 1 mol de oxígeno gaseoso contiene 6.023 * 10²³ moléculas de oxígeno.
Entonces, 6.25 moles contendrán:
= (6.25 × 6.023 * 10²³) moléculas de oxígeno.
≅ 3.764 × 10²³ moléculas de oxígeno.
(c) El número de átomos de oxígeno es:
= 2 × 3.764 × 10²³
= 7.528 × 10²³ átomos de oxígeno
(d) Usando la ecuación de gas ideal
PV = nRT
El volumen ocupado por el oxígeno =
Volumen ocupado por oxígeno =
Volumen ocupado por oxígeno= 14185.76 m³
