Answer:
5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Explanation:
Given data:
Moles of NO formed = ?
Moles of N₂ reacts = 2.86 mol
Solution:
Chemical equation:
N₂ + O₂ → 2NO
Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.
N₂ : NO
1 : 2
2.86 : 2/1×2.86 = 5.72 mol
So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Answer:
you can solve the rest of the equation. I only reduced it to that much to show you how to derive it
Answer:
Pentane » Hexane » Hexanol
Explanation:
Pentane and Hexane are simple molecular structured with discrete molecules having weak vanderwaals forces of attraction. But Hexane has high molecular mass than pentane hence pentane has lower boiling point than Hexane.
Hexanol has hydrogen bonds between highly electronegative oxygen atom and the hydrogen atom which break on high heat energy application hence it has high boiling point.
Answer:
A control variable in scientific experimentation is an experimental element which is constant and unchanged throughout the course of the investigation.
Hope this helped :)
