(8 points) Ammonia, NH3(g)and hydrogen chloride, HCl(g) react to form solid ammonium chloride NH4Cl(s).

NH3(g) + HCl(g) LaTeX: \longrightarrow⟶ NH4Cl(s)

Two 5.00 L flasks at 35.0.°C are connected by a stopcock. One flask contains 7.00 g of NH3(g) and the other contains 16.00 g of HCl(g) When the stopcock is open, the gases react until one is completely consumed. Which gas remains in the system after the reaction is complete? What will be the final pressure of the system after the reaction is complete? (Neglect the volume of the ammonium chloride formed).

TiliK225 [7]
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
                    (6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.

For a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k, calculate the inner diameter if you are designing for
bonufazy [111]

The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m

<h3>What is Stack Height ?</h3>

Stack height means the distance from the ground-level elevation at the base of the stack to the crown of the stack.

If a stack arises from a building or other structure, the ground-level elevation of that building or structure will be used as the base elevation of the stack.

Given is a steel stack that exhausts 1,200 cu.m/min of gases

P= 1 atm and

T= 400 K

maximum expected wind speed at stack height of 12 m/s

The formula for the diameter of chimney

\rm d=\sqrt{\dfrac{4Q}{\pi v} }

Q =1200 cu.m/min

= 1200 * 0.0166 = 19.92 cu.m/sec

Velocity = 12m/s

\rm d=\sqrt{\dfrac{4\times 19.92}{3.14*12} }\\

d= 1.45 m

Therefore The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m.
