Answer:
6.67 moles of NH₃
Explanation:
From the equation of reaction,
4NH₃(g) + 7O₂(g) → 4NO₂(g) + 6H₂O(g),
4 moles of NH₃ will produce 6 moles of 6H₂O,
X moles of NH₃ will produce 10 moles of H₂O
X = (10 * 4) / 6
X = 6.67 moles of NH₃
6.67 moles of NH₃ will produce 10 moles of H₂O
A general exponential expression is something like:
A^n
This means that we need to multiply the number A by itself n times.
Using that we will get (-2)^6 = 64
With that definition, we can rewrite:
(-2)^6 = (-2)*(-2)*(-2)*(-2)*(-2)*(-2)
So we just need to solve the above expression.
Also, remember the rule of signs:
(-)*(-) = (+)
We will get:
(-2)*(-2)*(-2)*(-2)*(-2)*(-2) = [(-2)*(-2)]*[(-2)*(-2)]*[(-2)*(-2)]
= 4*4*4 = 16*4 = 64
Then we got:
(-2)^6 = 64
