Ozone
Photochemical smog forms when sunlight reacts with vehicle exhaust emissions containing nitrogen oxides and volatile organic compounds, leading to the production of ground-level ozone. This ozone is a key component of smog and can result in respiratory issues and damage to vegetation.
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
The formation of smog occurs when ozone and vehicle exhaust react in sunlight. Smog is a type of air pollution containing ozone, nitrogen oxides, and volatile organic compounds that form ground-level ozone and fine particulate matter, contributing to health and environmental problems.
When sodium reacts with oxygen, it forms sodium oxide (Na2O).
Calcium reacts with fluorine to form calcium fluoride (the symbol is CaF2).
When magnesium reacts with nitrogen, it forms magnesium nitride (Mg3N2).
A rainbow forms when sunlight shines on water droplets in the atmosphere, causing the sunlight to be refracted, reflected, and dispersed. This process separates the sunlight into its different colors, creating the familiar multicolored arc in the sky.
