OxYgen and hydrogen particles are kept in a container. Which of the following accurately describes diffüsion of these gases?
OOxygen and hydrogen particles concentrate at the center of the container.
Oxygen particles move to one corner of the container and hydrogen particles go
to the opposite corner
DOxygen particles and hydrogen particles repel each other.
O Oxygen particles mix evenly with hydrogen particles.

Option D

Oxygen particles mix evenly with hydrogen particles.

Explanation:

Diffusion refers to the movement of gasses from a region of higher concentration to a region of lower concentration.

Diffusion occurs in gases because their particles are in a state of constant random motion.

Due to this continuous random motion, once the oxygen and the hydrogen are added to the container, they will begin to mix freely with each other until they fill up the entire volume of the container.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
