During the combustion of nh3, there is an increase in the amount of oxygen present, from 5 to 20 moles while the amount of nh3 remains unchanged. given this change in oxygen, what can we say about this chemical reaction?

Explanation:

The ratio of NH3 to NO produced will remain constant since NH3 is the limiting reactant.

Here in this reaction for every 4 moles of ammonia and 5 moles of oxygen gas , 4 moles of NO and 6 moles of water are formed.

So when the amount of oxygen gas is increased to 20 moles without changing the amount of ammonia , the amount of NO formed does not increase as ammonia becomes the limiting reactant.

i just learnt this recently but i need to look through my notes again

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
