Question

give two reason to show that ammonia is a compound of nitrogen and hydrogen and not a mixture of the two gases

Answer 1

U can say that ammonia is a compound by 5 reasons but u require 2 so the first one is GENERAL PROPERTIES: for a mixture , each constituent substance retains its own properties but for a compound, properties are entirely different from those of its constituent elements. Ammonia's properties are not same as nitrogen's or hydrogen's but it has its own. Secondly, SEPARATION OF CONSTITUENTS: for a mixture, constituents can be separated by physical methods based on differences in physical properties but for compound, constituent elements can only be separated by chemical methods, NOT by physical methods. Since nitrogen and hydrogen can be separated by physical methods as they have formed a new substance which is ammonia so chemical method is the only way. So from those 2 points u can prove and conclude that ammonia is a compound made up of nitrogen and hydrogen.

Answer 2

Answer:

Explanation:

It is a compound not amixture because it is made of nitrogen and hydrogen and there mass ratio will be same in every compound that is 14:3.

The other reason is that they can't be separated using separation techniques we have to chemical reaction to separate them
