Consider the equation below. N2 + 3H2 -> 2NH3 What is the mole ratio of hydrogen to ammonia?
2 answers:
The answer is: C. 3 : 2.
Balanced chemical reaction: 3H₂ + N₂ → 2NH₃.
From chemical reaction: n(H₂) : n(NH₃) = 3 : 2.
Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.
Coefficient in fron of hydrogen is 3 and coefficient in fron ammonia is 2.
Coefficients are important to prove the law of conservation of mass.

Answer:
pOH= 14.248
[H+]=1.77 M
[OH-]=5.65 x10^-15M
Explanation:
pH+pOH= 14
pOH= 14-pH
pOH=14-(-0.248)
pOH= 14.248
[H+]=10^-pH= 10^-(-0.248)=1.77 M
[OH-]=10^-pOH= 10^-14.248=5.65 x10^-15M

Answer:
30 minutes
Explanation:
If the plane is going 600 km/h
divide the length and time and it would be half of that, so 300 km would take 30 mins.
