Check all that apply. check all that apply. when two hydrogen atoms are very far apart, the potential energy approaches zero. when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed. when two hydrogen atoms that are far apart approach each other, the potential energy decreases. at a distance of 0.50 å the potential energy is less than that at 0.74 å. when the potential energy is zero, a covalent bond is formed.

when two hydrogen atoms are very far apart, the potential energy approaches zero.

when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed.

Explanation:

As we know that the potential energy of two charges is given as

here as the the distance is very large the potential energy is least

at r = infinite

so as two hydrogen atoms comes closer the distance will decrease and hence the potential energy will increase.

So covalent bond is formed when two atoms are close enough so that the equilibrium is achieved

so correct answer will be

when two hydrogen atoms are very far apart, the potential energy approaches zero.

when the distance between two hydrogen atoms is 0.74 å, a covalent bond is formed.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
