Which is the best example of a compound?
Examples of Compounds:
- Water – Formula: H2O = Hydrogen2 + Oxygen.
- Hydrogen Peroxide – Formula: H2O2 = Hydrogen2 + Oxygen2
- Salt – Formula: NaCl = Sodium + Chlorine.
- Baking Soda – Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3
- Octane – Formula: C8H18 = Carbon8 + Hydrogen18
What is the correctly describes a compound?
Answer Expert Verified A chemical compound can be described as substance composed of atoms from more than one element held together by chemical bonds in a fixed stoichiometric proportion. A compound has different physical and chemical properties from its constituent elements.
Which of the following describes a compound 2 points?
Answer: A compound is two or more types of atoms chemically joined together.
Which example describes a compound?
A compound is a substance formed when two or more chemical elements are chemically bonded together. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
IS elements and compounds are both pure substances?
Elements and compounds are both examples of pure substances. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen.
Which of the following is the best way of differentiating elements and compounds?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What is difference between an element and a compound?
An element is made up of one type of atom only. A compound is a substance made up of two or more atoms of different elements chemically joined (or bonded) together. For example, carbon dioxide gas (CO2) consists of one carbon atom and two oxygen atoms bonded together.
Is air an element or compound?
Air is a mixture but not compound. Its constituents can be separated. For example: oxygen, nitrogen etc.
What is the chemical formula of air?
There is no chemical formula for air as it is a mixture of many compounds. The major components would be Nitrogen (N2), Oxygen (O2), Carbon Dioxide (CO2), Water (H2O), and many others in minute amounts. Nitrogen makes up 78.1% of air, while oxygen makes up 20.9% of air.
