Nitrogen and water react to form nitrogen monoxide and hydrogen, like this: N2(g) + 2H2O(g) → 2NO(g) +2H2(g) Also, a chemist fin
Thepotemich [5.8K]

Answer:

Kc for this reaction is 0.43

Explanation:

This is the equilibrium:

N₂(g) + 2H₂O(g) → 2NO(g) +2H₂(g)

And we have all the concentration at equilibrium:

N₂: 0.25M

H₂ : 1.3M

NO: 0.33M

H₂: 1.2M

They are ok, because they are in MOLARITY. (mol/L)

Let's make the expression for Kc

Kc = ( [NO]² . [H₂]² ) / ([N₂] . [H₂O]²)

Kc = (0.33² . 1.2²) / (0.25 . 1.2²)

Kc = 0.4356

In two significant digits. 0.43

1. 7.000 mmhg = ______ KPa?<br> 2. 10.00 kPa = ________atm?<br> 3. 15.00 kPa______mmHg?
Minchanka [31]
1 kPa = 7.5 mmHg so 7.0 mmHg / 7.5 mmHg x 1 kPa = .93 kPa

101.3 kPa = 1 atm so 10 kPa / 101.3 kPa x 1 atm = .0987 atm

1 kPa = 7.5 mmHg so 15 kPa x 7.5 mmHg / 1 kPa = 112.5 mmHg

If a microwave oven emits 1,100 J of energy every second, how long will it take for the microwave to emit 4650 J of energy? Expr
icang [17]

Answer:

Time = 4.2273 seconds

Explanation:

The amount of the energy emitted by the microwave = 1100 J/s

It means that :

1100 J of the energy is emitted in 1 second

Also,

1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second

To calculate:

Time for emitting 4650 J of energy

Thus,

4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second

<u>Time = 4.2273 seconds</u>
