<span>Using a mixture of water, sand, and chemicals under high pressure to free tightly held oil and natural gas is known as Hy</span>draulic fracturing.

This is a process commonly practiced in the United states where millions of gallons of water, sand, and chemicals are pumped underground. This is used to break apart the rock bed and release the gases that are deep in the ground.</span>
The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
Answer:
When an electron moves from a higher to lower orbital, energy is released as waves of light.
Explanation:
The energy from the flame excites the electrons to orbitals of higher energy.
When the electrons drop to lower-energy orbitals, they release the excess energy as light waves.
