what would happen if oxygen is not available on earth for 5 seconds

Horribality
Explanation:
Everyone at the beach would get sunburns. Ozone is molecular oxygen and blocks the majority of UV light. Without it, we are toast.
The daytime sky would get darker. With fewer particles in the atmosphere to scatter blue light, the sky would get a bit less blue and a bit more black.
Every internal combustion engine would stall. This means that every airplane taking off from a runway would likely crash to the ground, while planes in flight could glide for some time.
All pieces of untreated metal would instantly spot-weld to one another. This is one of the more interesting side effects. The reason metals don’t weld on contact is they are coated in a layer of oxidation. In vacuum conditions, metal welds without any intermediate liquid phase (Cold welding).
Everyone’s inner ear would explode. As mentioned, we would lose about 21 percent of the air pressure in an instant, equivalent to being teleported to the top of the high Andes (elevation, about 2,000 meters).
Every building made out of concrete would turn to dust. Oxygen is an important binder in concrete structures (really, the CO2 is), and without it, the compounds do not hold their rigidity.
Every living cell would explode in a haze of hydrogen gas. Water is one third oxygen; without it, the hydrogen turns into gaseous state and expands in volume.
The oceans would evaporate and bleed into space. As oxygen disappears from the oceans’ water, the hydrogen component becomes an unbound free gas. Hydrogen gas, being the lightest, will rise to the upper troposphere and slowly bleed into space through Atmospheric escape.
Everything above ground would immediately go into free fall. As oxygen makes up about 45 percent of the Earth’s crust and mantle, there is suddenly a lot less “stuff” beneath your feet to hold everything up.
If it was just 5 seconds, we wouldn’t notice changes in our breathing.
But do you know what would happen around us?
Earth’s crust contains 45% oxygen. Without oxygen, crust would crumble, causing the ground to crumble and we would be in freefall. Buildings, bridges and concrete structure would crumble into dust, as oxygen is the binding agent for concrete. Cars would stop, and planes would fall from sky as their combustion engines wouldn’t work without oxygen. Also, losing oxygen means losing almost 21% air pressure. This would cause our inner ear to explode, causing hearing loss. It would also become darker suddenly.
Do you know why?
For sunlight to reach us, it needs to bounce off air particles like oxygen, dust etc. No oxygen means much fewer particles to bounce off, thus much darker.
