Using only oxygen, molecular oxygen and ozone. If combined with something else, it can be a number of things: * If combined with a metal, it is called an oxide. * If part of a chemical that could be formed without it, it is called a peroxide. * If attached to hydrogen, it can be hydroxide, water, oxonium or hydronium. * If attached to carbon by a single bond, it is an alcohol. * If by two bonds to the same carbon, it is an aldehyde or a ketone. * If by a single bond to two carbon atoms, it is an ether. * Three oxygen bonds to the same carbon are a carboxyl. * If the fourth oxygen bond is with hydrogen, it is a carboxylic acid; if with another carbon, it is an ester; if witha salt, it is a soap. * If in a carbon ring, it can be a sugar. and there are many more chemicals that have further specific names.
Substances are either elements or compounds. Elements are substances in their simplest form that cannot be separated further through chemical reactions. Examples of elements are oxygen (O2), carbon (C2), and hydrogen (H2). Compounds are compositions of two or more elements. Examples of compounds are water (H2O), carbon dioxide (CO2), and sodium chloride - table salt (NaCl).
dissolved oxygen is dissolved oxygen
Elements are atoms that consist of different protons. They are the simplest thing that defines an atom. The only thing that defines them is the number of protons, electrons and neutrons they have, as all protons, electrons and neutrons are identical. (I think) Compounds are elements joined chemically together. They must be in a set ratio (e.g. water must be 2 hydrogen atoms and 1 oxygen atom) They can only be separated chemically (e.g electrolysis). Mixtures are stuff that contain different substances or materials. They are not bonded together chemically. There is no set ratio, unlike compounds. They can be separated by physical methods. (for example, salt in water is a mixture. They can be separated by distillation.)
compounds are bonded at a molecular level. they would hve to be releived of that bond before physical separaion can occur.
A compound comprises the same proportion of its components, a mixture can be made up of varying amounts.A compound may have physical and chemical properties which are quite different to those of any of its components. A mixture retains many of the physical and chemical properties of its main ingredient.
magnesium and oxygen are elements. They are not compounds
No, oxygen cannot be liberated from all oxygen-containing compounds. Some compounds contain oxygen in a very stable form, such as in water (H2O), where the oxygen is tightly bound to hydrogen. Releasing oxygen from these compounds would require significant energy input.
Water and vinegar are both compounds, oxygen is an element.
Ozone
The oxidation number for oxygen in most compounds is -2.
OxygeN
true
Oxygen and chlorine are each elements, not compounds. They combined to form a number of covalent compounds because they are both nonmetals.
Nonmetals burning in oxygen form covalent type compounds, as compared to metals which form ionic compounds.
As fluorine is more electronegative than oxygen, fluorine acts as the electron acceptor in the compounds with oxygen. As fluorine becomes partially negative charged and positive for oxygen, they are called fluorides.
Water, quartz, rust, and sugar are all common, important compounds containing oxygen.
yes. If the metal is reactive enough then oxygen naturally forms compounds.(oxides)
