For example, the theoretical probability for the coin toss it will be 50% chance for either side. For the experimental it depends on your own results.

How many moles of NH3 will be produced if 2 moles of N2 reacts with excess H2 gas?
skad [1K]

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

J is now (0, -2)      multiply by 2
J was     (0, -4)
