Answer:
13 mol NO
Explanation:
Step 1: Write the balanced equation
4 NH₃(g) + 5 O₂(g) ⇒ 4 NO(g) + 6 H₂O(g)
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to NO is 5:4.
Step 3: Calculate the number of moles of O₂ needed to produce 16 moles of NO
We will use the previously established molar ratio.
16 mol O₂ × 4 mol NO/5 mol O₂ = 13 mol NO
 
        
             
        
        
        
Answer is: C alkane.
Name of this molecule is n-hexane.
Hexane is alkane (acyclic saturated hydrocarbon, carbon-carbon bonds are single) of six carbon atoms. 
Carbon atoms in hexane have sp3 hybridization.
In sp3 hybridization hybridize one s-orbital and three p-orbitals of carbon atom.
Alkene has one double bond and alkyne has one triple bond.
