The answer to this is: a molecule
a. chlorofluorocarbons
Explanation:
The chemical reaction describes the combination of chlorofluorocarbons with ozone.
Reaction 1: ClO + BrO ⇒ Cl + Br + O₂
Reaction 2: Cl + O₃ ⇒ ClO + O₂
Reaction 3: Br + O₃ ⇒ BrO + O₂
O₃ is the ozone molecule, the Cl, and Br are the chlorofluorocarbons.
- In this reaction, ozone is converted into oxygen gas. This reaction takes place in the stratosphere.
- This leads to the penetration and creation of a hole in the atmosphere which allows for ultraviolet rays to reach the earth surface.
- The chlorofluorocarbons are produced on the earth surface in component gases used for making refrigerants, car sprays, air conditioners etc.
- When the reach the ozone layer, they react with it and produce oxygen gas.

The length of the inclined plane is approximately 12 ft
The situation forms a right angle triangle.
<h3>Right triangle</h3>
Right triangle have one of its angle as 90 degrees.
Therefore,
The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.
height = 4 ft
angle(∅) = 19.45°
sin 19.45 = 4 / h
h = 4 / 0.33298412235
h = 12.0125847796
h = 12 ft
Therefore, the length of the inclined plane is approximately 12 ft
