Answer:
The main energy levels are the shells where the electron resides in a location that's relative to the atom's nucleus.
Explanation:
In electronic configuration in chemistry, the main energy levels are the shells where the electron resides in a location that's relative to the atom's nucleus. Such an energy level is usually denoted by the principal quantum number n. So n can be 1,2,3,4...e.t.c
Answer:
option A
Explanation:
because acid comes from preparation of fossil fuel
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.
