Alkanes: Alkanes are those organic compounds in which carbon only form single bond with another carbon atom. General formula of Alkane is CnH2n+2. Ex~ Methane Ethane Propane Butane Pentane And more..
Sodium react with Oxygen to form: SodiumOxide Sodium react without oxygen to form sodium oxide. 4Na(s)+O2(g)---->2Na2O(s) Here, Sodium is metal which is in solid state. Oxygen is nonmetal which is in gaseous state. In above reaction, Na loses one electron to form Na+ cation and Oxygen gain two electrons to form O2-anion to complete octet for stability.Finally, these bothcation and anion forms a compound Na2O .
