Why oxygen is more electronegative than helium?
Oxygen has more protons in its nucleus compared to helium, creating a stronger pull on electrons, leading to higher electronegativity. Additionally, oxygen has a smaller atomic size, allowing it to hold on to electrons more tightly, enhancing its electronegativity compared to helium.
What happens to the voice of a diver breathing in a mixture of oxygen and helium?
When a diver breathes in a mixture of oxygen and helium, their voice will sound higher in pitch due to the different density and speed of sound in helium compared to air. The helium molecules vibrate more quickly in the vocal cords, resulting in the higher pitch.
Is oxygen gas also known for helium?
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
Which of the two has more force of attraction helium or oxygen?
Oxygen has a stronger force of attraction compared to helium because oxygen has a higher atomic number and more protons, resulting in stronger electrostatic forces between its nucleus and electrons.
Does helium dissolve into oxygen?
No, helium does not dissolve into oxygen. Helium is a non-reactive gas that remains separate from other gases in a mixture.
What is the ratio of velocity of sound in helium to that the oxygen at the same temperature and pressure?
The ratio of the velocity of sound in helium to that in oxygen at the same temperature and pressure is approximately the square root of the ratio of their molecular weights. Since helium is about four times lighter than oxygen (molecular weight of helium is 4 g/mol and oxygen is 32 g/mol), the ratio would be approximately √(32/4) = 2.
What is made from 15g of oxygen and 5g of helium?
There isn't a specific compound that can be made using 15g of oxygen and 5g of helium, as oxygen and helium do not readily react with each other to form compounds. However, both oxygen and helium are gases at standard conditions.
What is ligther helium or oxygen?
Helium---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----
Is helium oxygen?
No. Helium and oxygen are two different elements.
What is the mixture 15ml of oxygen and 5ml of helium?
A mixture of oxygen and helium is used in diving.
How are helium and oxygen different?
Helium is completely inert. Oxygen will react with many substances.
Can hydrogen and oxygen make helium?
Hydrogen an react with oxygen to form water and not helium
