yan [13]

Answer:

0.66atm

Explanation:

Based on the reaction:

NH₄HS(s) ↔ NH₃(g) + H₂S(g)

The equilibrium constant, Kp, is defined as:

Kp = 0.11 = P_{NH_3} P_{H_2S}

As moles of gas produced for NH₃(g) and H₂S(g) are the same, it is possible to write:

0.11 = P_{NH_3}^2

0.33 = P_{NH_3}

That means pressure of NH₃(g) is 0.33atm and H₂S(g) is, also, 0.33atm. Thus, total pressure is:

0.33atm×2 = <em>0.66atm</em>

A stone is dropped from the roof of a building; 2.00s after that, a second stone is thrown straight down with an initial speed o
Brut [27]
A) -0.5(9.8)*t^2 = -25(t-2) - 0.5(9.8)(t-2)^2 
-4.9t^2 = -25t + 50 - 4.9(t^2-4t+4) 
0 = -25t+50+19.6t - 19.6 
5.4t = 30.4 
t = 5.62962963 s 

b) h = -4.9(5.62962963)^2 
h = -155.2943759 
the building is 155.2943759 m high 

c) speed 0of first stone 
= at 
= 9.8*5.62962963 
= 55.17037037 m/s 
speed of second stone
= v + at
= 25+9.8*3.62962963 
= 60.57037037 m/s
