<u>Ans: O2 because it produces only 0.20 mol of NO</u>
<u>Given:</u>
Mass of NH3 = 4.0 g
Mass of O2 = 8.0 g
<u>To determine:</u>
The limiting reagent in the given reaction
4NH3 + 5O2 → 4NO + 6H2O
<u>Explanation:</u>
# moles of NH3 = 4.0/17 g.mol-1 = 0.2353 moles
# moles of O2 = 8.0/32 = 0.25 moles
Based on the reaction stoichiometry:
1 mole of NH3 produces 1 mole of NO
Therefore, 0.2353 moles of NH3 will produce: 0.2353 moles of NO
Similarly, 1 mole of O2 will produce 4/5 moles of NO
0.25 moles of O2 will form: 0.25*4/5 = 0.2 moles of NO
Thus, O2 is the limiting reactant.
I think its Helium correct me if I'm wrong plz.
Answer:Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics.
