Answer:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp

Explanation:

The reaction is:

2NO + 2H₂ → N₂ + 2H₂O

The expression for Kp (pressure equilibrium constant) would be:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²

There is another expression for Kp, where you work with Kc (equilibrium constant)

Kp = Kc (R.T)^Δn

where R is the Ideal Gases constant

T° is absolute temperature

Δn = moles of gases formed - moles of gases, I had initially

If 832J of energy is required to raise the temperature of a sample of aluminum from 20.0° C to 97.0° C, what mass is the sample
LiRa [457]
Data:
Q (Amount of heat) = 832 J
m (mass) = ?
c (Specific heat) = <span>0.90 J/(g × ° C)
T (final) = 97 ºC
To (initial) = 20 ºC
</span>ΔT = T - To → ΔT = 97 - 20 → ΔT = 77 ºC

Formula:
Q = m*c*ΔT

Solving:
Q = m*c*ΔT
832 = m*0.90*77
832 = 69.3m
69.3m = 832
m =  \frac{832}{69.3}
\boxed{\boxed{m \approx 12.00\:g}}\end{array}}\qquad\quad\checkmark

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, l, ml, an
vfiekz [6]
First, since l = n-1,
5,4,-5,1/2 and 2,1,0,1/2 are the only answer choices left.
Next, since ml = -l to l,
2,1,0,1/2
is the answer because in 5,4,-5,1/2, the ml value of -5 is not in the range of -4 to 4, as notes by the value 4 for l.

A car is traveling at 87.0 km/hr. How many meters will it travel in 37.0 seconds?
Alenkasestr [34]

Speed of the car = 87.0 \frac{km}{hr}

Given time = 37.0 s

Converting time from seconds to hours:

1 hr= 60 min; 1 min = 60 s

37.0 s * \frac{1 min}{60s}*\frac{1 hr}{60min}  = 0.0103 hr

Calculating distance from speed and time:

0.0103 hr * \frac{87.0 km}{1 hr} =0.894 km

Converting distance from km to m:

0.894 km * \frac{1000 m}{1 km} = 894 m

So the distance traveled by the car in 37.0 s is 894 m.
