Ozone is not classified as particulate.
A particulate is a very small solid particle that can exist in suspension in both liquid and a gas. This particle remains suspended because it does not dissolve in the liquid or gas that it is suspended in. Dust and ash are capable of being particulates in both gases and liquids. Lead has been known to be a particulate in water, acting as a contaminant.
On the other hand, ozone is a gas that exists as a molecule of three oxygen atoms bonded together. For this reason, Ozone can not be particulate. The correct answer is A.Ozone.
Air is a mixture of gasses, including nitrogen, oxygen, carbon dioxide and water vapour, as such it is always chemically impure.
Answer:
The answer to your question is [NObr] = 1.41
Explanation:
Data
Kc = 2
[NO] = 2 M
Br₂ = 1.0 M
NOBr = ?
Process
1.- Write the Equation of the Kc
Kc =
2.- Solve for [NOBr]
[NOBr]² =
3.- Substitution
[NOBr]² =
4.- Simplification
[¨NOBr]² =
[NOBr]² = 2
5.- Result
[NOBr] =
[NOBr] = 1.41
Answer:
It is true that earth was once covered with oceans and little dry land.
Explanation:
Over the course of around four billion years, the Earth's oceans have lost about a quarter of their original mass. Today the atmosphere is rich in oxygen, which reacts with both hydrogen and deuterium to recreate water, which falls back to the Earth's surface. So the vast bulk of the water on Earth is held in a closed system that prevents the planet from gradually drying out. According to the researchers, the continents emerged relatively suddenly from an ocean that covered 95 percent of the Earth's surface. The appearance of large masses of dry land would have caused more extreme weather, changes in ocean currents and the emergence of proper seasons. In turn, these environmental changes may have led to rise in atmospheric oxygen that enabled the explosion of new life forms around 500 million years ago.
