Consider the reactions _1 2 n2(g) + _1 2 o2(g) → no(g) _1 2 n2(g) + o2(g) → no2(g) if these reactions come to equilibrium after combustion in an internal-combustion engine at 2000 k and 200 bar, estimate the mole fractions of no and no2 present for mole fractions of nitrogen and oxygen in the combustion products of 0.70 and 0.05.

Explanation:

Base of calculation: 100 mol

Initially in air :

79% N2

21% O2

Equilibrium:

Knowing that:

(1)

 (2)

Solving 1 and 2:

Fractions:

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
