This is a decomposition reaction.
Neither, because silicon is an element, not a compound.
Any dioxide has two (= 'di-') oxygen atoms (= 'oxide') in its molecular formula. Examples: Carbon dioxide CO2 and Sulfur dioxide SO2
No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
Yes
Neither, because silicon is an element, not a compound.
Carbonic acid is a compound, not an element. It is formed from the chemical reaction of carbon dioxide and water.
Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element
Carbon monoxide (CO) and carbon dioxide (CO2) are molecular compounds containing the elements carbon and oxygen. There is no compound named carbon oxygen.Added:Carbon is an element, atomic symbol C.Oxygen is an element, di-atomic molecule with symbol O2.Carbon dioxide is a compound with molecular formula CO2, where the two elements (C and O2) are bonded together.Carbon monoxide is a compound, (very different from carbon dioxide), with molecular formula CO, where the two elements (C and O2) are bonded together in a different way.
oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one element.
yes
According to the rules of nomenclature for molecular compounds, "carbon" means 1 carbon (the absence of a prefix in the first element of a molecular compound means there's just one) and "dioxide" means 2 (the prefix di- means 2.) If, by chance, the second element of a molecular compounds has 1, then you do use the prefix mono-, for example, carbon monoxide. However, a molecular compound never starts with mono-. If there's just one, you omit the prefix on the first of the two elements. So, carbon dioxide means 1 carbon, 2 oxygens, so CO2.
Oxygen is an element. In the air it is mixed with Nitrogen, Carbon Dioxide, etc.
No, an element is the simplest form of matter.
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.
No Hg, or Mercury is an element, but it is not molecular.
No. It's a molecular element.
