First you need to know the value of Kp for this reaction. The reaction is: SO2 (g) + 2 H2S (g)<=> 3S(s) + 2 H2O(g): Kp = PH2O^2 / PSO2(PH2O)^2 but since the problem is lacking in details.
Otherwise, let x = PSO2 = PH2S. Then:
Kp = (22/760 atm)^2 / x^3
x = cube root (0.289)/Kp = PSO2
But if the kp is given, let us assume it is 8.0*10^15The solution would be:convert the given pressure of water to atm, which is: 0.029
Kp=P(H2O)^2/P(SO2)P(H2S)^2
8.0*10^15 = (0.029)^2/x^3
(8.0*10^15).(x^3)=8.41*10^-4
take the cube root of both sides(2.0*10^5).x = 9.439130*10^-2x = P (SO2) = 4.6*10^-7
Answer:
c. A flat board tilted at an angle
Explanation:
form the looks of it, and i dont wanna sound like a flat earther her, cuz im not '-', but the best option here would be the flat board at an angle becasue the earth is tilted and isnt even like it said in the prompt.
Hope this helped and idrc about brainliest :)
Answer:
Light pollution is excessive, misdirected or inappropriate outdoor lighting. Too much light pollution washes out the view of the Universe, increasing energy consumption, interferes with astronomical research, disrupts ecosystems, and affects the health and safety of humans and wildlife.
Explanation:
Light pollution radically alters their nighttime environment by turning night into day. ... “Predators use light to hunt, and prey species use darkness as cover,” Kyba explains “Near cities, cloudy skies are now hundreds, or even thousands of times brighter than they were 200 years ago.
Answer:- 28.9 grams of CO are needed to react with 55.0 grams of Iron(II)oxide.
Solution:- The balanced equation for the given reaction is:
From this equation, 1 mol of Iron(II)oxide reacts with 2 moles of carbon monoxide. First of all we convert given grams of Iron(II)oxide to moles and multiply by the mol ratio to get the moles of CO. Further the moles of CO are multiplied by it's molar mass to find out it's grams.
Molar mass of is 159.69 gram per mol and the molar mass of CO is 28 gram per mol. The calculations are shown below:
= 28.9 g CO
So, 28.9 grams of CO are needed to react completely with 55.0 grams of Iron(II)oxide.
