Substances which can oxidize molecular Oxygen(O2) are =
Fluorine(F2) - It will oxidize Oxygen to +2 oxidation state:
F2 + O2 ----> OF2 (Oxygen difluoride)
Platinum(VI) Fluoride - It will oxidize Oxygen to +1/2 Oxidation state:
O2 + PtF6 ----> O2PtF6 (Dioxygenyl Hexafluoroplatinate)
copper and oxygen
magnesium and oxygen are elements. They are not compounds
OF2 is a molecular compound. Oxygen difluoride (OF2) consists of covalent bonds between oxygen and fluorine atoms, with a molecular structure that does not involve the transfer of electrons between elements typical of ionic compounds.
oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one element.
Calcium acetate and potassium hydroxide are molecular compounds as they are composed of nonmetal elements. Nitrogen monoxide is also a molecular compound, consisting of nitrogen and oxygen elements bonded together covalently.
Sodium carbonate has sodium, carbon and oxygen in it, and the molecular formula is NaCO. Sodium hydroxide is consists of the elements sodium, oxygen and hydrogen and it has the molecular formula NaOH. One of the common features of both these compounds are being alkali in aqueous medium.
When sulfur and oxygen combine, they form a molecular compound, specifically sulfur dioxide (SO2). This compound is held together by covalent bonds, where the atoms share electrons. Ionic compounds result from the transfer of electrons between elements.
Most metals exist in Earth's crust as compounds because they are highly reactive and tend to combine with other elements to form stable compounds. These compounds are more stable and less likely to oxidize compared to pure metals. As a result, metals are found in nature as ores, which are mineral compounds containing the metal along with other elements.
Oxygen in its non-molecular form exists as an oxygen atom, denoted as O. It is a highly reactive element that can combine with other elements to form various compounds. Oxygen atoms freely exist in the Earth's atmosphere and play a crucial role in supporting life through the process of respiration.
A binary molecular compound is a chemical compound composed of two different nonmetal elements. Out of the options provided, PCl5 and AgI are binary molecular compounds because they consist of two different nonmetal elements (i.e., phosphorus and chlorine for PCl5 and silver and iodine for AgI). MgS and BeHCO3 are not binary molecular compounds as they contain a metal element (magnesium and beryllium) combined with nonmetal elements (sulfur and hydrogen, carbon, oxygen) respectively.
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
Oxygen typically forms compounds with elements such as hydrogen, carbon, nitrogen, and metals like iron and magnesium. These elements can participate in chemical reactions with oxygen to form oxides or other compounds.
