How do you know the difference between a compound and mixture?
Compound:a substance that is made up of more than one type of atom bonded together. Mixture: a combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.
What is a true compound?
Two things are true of all compounds: A compound always has the same elements in the same proportions. For example, carbon dioxide always has two atoms of oxygen for each atom of carbon, and water always has two atoms of hydrogen for each atom of oxygen. A compound always has the same composition throughout.
What is the common name for the compound H2O?
dihydrogen monoxide
How many known compounds are there?
Because of the great variety of ways that carbon can bond with itself and other elements, there are more than nine million organic compounds. The compounds that are not considered to be organic are called inorganic compounds (see below Inorganic compounds).
What is a fun fact about a compound?
They have unique chemical structures based upon their parts, and their atoms are held together by chemical bonds. Interesting Compounds Facts: There are defined proportions for the elements that make up a chemical compound, and they are in direct ratios.
What are 5 facts about compounds?
Compounds
- Oxygen. Oxygen is a colorless gas.
- Hydrogen. Hydrogen is a light, colorless gas that reacts with oxygen to make water.
- Hydrogen. Hydrogen is an element, meaning it only contains one kind of atom.
- Chemical reaction. Hydrogen and oxygen can come together in a process called a chemical reaction.
- Water.
Can a compound be made of the same element?
A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds. Types of compounds include covalent and ionic compounds.
