Short Answer TypeNitrogen forms five stable oxides with oxygen of the formulae N2O, NO, N2O3, N2O4, N2O5. This oxide formation explains which law of chemical combination?
How many number of moles of oxygen atoms are present in 0.6 mole of hydrated oxalic acid (COOH)22H2O?
27 g of Al will react completely with, how many grams of oxygen?
The balanced equation for the given reaction is:
4 Al+ 3 O2 --------> 2Al2O3
Atomic mass of Al = 27g
Atomic mass of O2 = 2 × 16 = 32g
Mole ratio of aluminium and oxygen can be given as:
Al : O2
4 : 3
1 : 3/4
Mass of O2 required = 3/4 × 32 =24g
