Answer:
2 moles of N₂ will produce 4 moles of NH₃
Step-by-step explanation:
Equation of reaction
N₂ + 3H₂ → 2NH₃
The process above is the Born-Harber method of producing ammonia NH₃ industrially.
From the equation of reaction,
1 moles of N₂ will produce 2 moles of NH₃
1 moles N₂ = 2 moles NH₃
2 moles of N₂ = x moles of NH₃
x = (2*2) / 1 = 4moles of NH₃
2 moles of N₂ will produce 4 moles of NH₃
Well for answer 23 is -6 √(5) + 6 √(2).
The answer for 25 is -3 √(5) - 2 √(6)
And the answer for 27 is -15 √(5) + 4 √(3) + 3 √(6)
Hope this helps :)
First you need to multiply by a factor that will givr you the same value in one of the x or y value.
(6x-12y=24)1
+(-x-6y=4)-2
6x-12y=24
=2x+12y=-8
8x=16÷8
x=2
now that you have x, substitute x by 2 in one of the eqauations
-2-6y=4
+2. +2
=-6y=6
÷-6. ÷-6
y=-1
