Answer:
An element is a pure substance that cannot be broken down into simpler substances by chemical means. Elements are made up of only one type of atom. For example, oxygen and hydrogen are elements.
A compound is a substance made up of two or more different elements chemically bonded together in a fixed ratio. The elements in a compound are held together by chemical bonds. For example, water (H2O) is a compound made up of hydrogen and oxygen atoms.
A molecule is a group of two or more atoms held together by chemical bonds. Molecules can be made up of atoms from the same element or different elements. For example, oxygen gas (O2) is a molecule made up of two oxygen atoms bonded together.
In summary, an element is a pure substance made up of only one type of atom, a compound is a substance made up of two or more different elements chemically bonded together, and a molecule is a group of atoms held together by chemical bonds.
Answer: An element is the simplest substance. There are many unique elements but they are all different and cannot be broken down any further and still have their own characteristics. A molecule is 2 or more atoms that are chemically bound. A compound molecule is a molecule(2 or more atoms) that is made of 2 or more elements.
Explanation: atoms that are chemically bound Molecule=2 or more
The answer is: B) Spills in your shop and any releases on pavement or outside should be poured down a drain.
Pouring used oil down a drain can cause damege to environment.
Oil is nonpolar substance and does not dissolve in the water (polar molecule), used oil remain existent in the drain and sewer or in the environment.
Small spills create a cumulative effect with significant impact on the environment.
Untended spills inside a shop can spread to an inside drain connected to the storm sewer system and cause floods.
Answer:
The higher latitude may have a colder climate than the lower latitude
Explanation:
For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun's rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.
