Compounds are pure substances formed from two elements (elements are pure as well) joining together. this creates a molecule, A compound is also known as a mixture of elements. these are only possible if the elements that form the molecule (compound) are pure. For example, a water molecule contains from two Hydrogen atoms combining with one Oxygen atom. This creates the compound known as H2O the 2 means that their are two Hydrogen atoms and since there is no subscript for Oxygen (Subscript=x or 2and so on)

It is true for all compounds Composition of ionic compounds Which is NOT true of compounds Which is?
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.

Why using dark colored reagent bottles in storing in storing some chemicals?
Some chemical compounds are sensitive to light. The dark colored bottle prevents light from getting to the contents. The same is true for things like beer and medicines.
Is it true that some organic compounds do not have carbon?
No, all organic compounds contain carbon as their essential element. The definition of organic compounds is based on the presence of carbon atoms, although some inorganic compounds may also contain carbon.
Very few minerals are compounds true or false?
False. Most minerals are compounds, which means that they are combinations of elements. Additionally, some minerals are elements by themselves.
What are most things elements or compounds?
Compounds.
Are compounds are chemically bonded togrther true or false?
true!
What are compounds made by living things called?
Organic compounds made by living things are called carbon compounds. This is because carbon is required by all living things to function.
Is it true that unknown compounds can usually be identified based solely on their physical properties.?
