Explanation:
You are breathing in dinitrogen and dioxygen. You exhale dinitrogen and carbon dioxide. And the atmosphere contains traces of other gases. You drink water. You have a wash with water, and soap. You eat carbohydrates and proteins. You ride to work on a vehicle powered by hydrocarbons, which spits out carbon dioxide exhaust fumes, and also some nitrogen oxides. And so your exposure to chemicals is pervasive, and unavoidable.

Answer:
A cup of boiling water.
Explanation:
Due to their mobility, particles in a substance contain kinetic energy. The average kinetic energy of the particles increases with temperature.
Since hot water has the highest temperature of the available possibilities in this situation, it has the highest average kinetic energy. Compared to particles in icy water, warm water, or room temperature water, those in hot water are moving more quickly and possess more energy.
For instance, when hot water is compared to frozen water, the particles in the hot water are moving more quickly due to the higher temperature. The lower temperature of ice water causes the particles to move more slowly. A difference in average kinetic energy results from this difference in velocity.
b. metals.
c. halogens.
d. noble gases.
The elements that do not ordinarily form compounds are noble gases as they have complete octet.
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number of the element.All atoms with same atomic number are atoms of same element.

b.It is a heterogeneous catalyst, so only a small amount is needed and it is easily separated from the products.
c.It is a homogeneous catalyst, so although a large amount is needed, it is easily separated from the products.
d.It is a heterogeneous catalyst, so a large amount is needed and it exits with the products.
