A compound composed of nitrogen and hydrogen was burned completely.1.5g of nitrogen monoxide and 1.35g of water are formed after this reaction.Whta is the empirical formula of the compound?(Ar:H=1,N=14,O=16)

Answer:
pressurethen they possess equal volumes.SAQ 1: Suppose you have been given three gas cylinders of equal volume (5 litres) containingthree gases N2, O2 and H2. Each of them has a pressure of 2 atmospheres at temperature of270C. If nitrogen cylinder contains 20, 00, 000 molecules, then find out the number of moleculesof oxygen and hydrogen present in the other cylinders.SAQ 2.There are 1 lack molecules each of NO and SO2 in two different cylinders of V litrecapacity each at 300C. The pressure in NO cylinder is 860 mm of mercury. What is the pressurein the SO2 cylinder?Experimental validity:Avogadro's law explained satisfactorily the Gay Lussac's Law of combining gaseous volumes.In fact the success of the Avogadro's law is based on the Gay Lussac's experimental observations.Gay Lussac experimentally found that:Under identical conditions of temperature and pressure, if gaseous reactants completely reactto give gaseous products then there exists a whole number ratio always between the volumes ofthe reactants and products.(i) 1 volume of hydrogen gas combines with 1 volume of chlorine gas to give2 volumes of hydrogen chloride gas(ii) 2 volumes of hydrogen gas combine with 1 volume of oxygen gas to give2 volumes of water vapourAvogadro's law (the then hypothesis) could corroborate the Gay Lussac's findings stated above.Two assumptions made by Avogadro were tha
