What volume of hydrogen sulfide is needed to cause coma in a room 10mX8mX4m?
For hydrogen sulfide, inhalation of a single breath at a concentration of 1000 ppm ( 0.1% ) may cause coma. What volume of hydrogen sulfide is needed to achieve this level in a room of dimensions 10m x 8m x 4m?
admin answers:
The room is 320 m^3 you will need 0.32 m^3 of hydrogen sulphide, or 320 litres.

Ammonium hydrogen sulfide dissociates into ammonia gas and hydrogen sulfide gas. If we start with a sample of?
Ammonium hydrogen sulfide dissociates into ammonia gas and hydrogen sulfide gas. If we start with a sample of pure NH4HS(s) at 25°C, the total pressure of the gases is 0.658 atm when equilibrium is established. Write an equation for the dissociation reaction and determine the value of Kp. (Type your answer using the format CO2 for CO2. Use the lowest possible coefficients.)
admin answers:
NH4HS(s) ==> NH3(g) + H2S(g)
Total pressure at equilibrium = 0.658 atm
Individual pressure of each gas = 0.329 atm
Kp = (0.329 atm)^2 = 0.108

How many grams of sodium sulfide are formed if 16.47 g of hydrogen sulfide is bubbled into a solution containi?
When hydrogen sulfide gas is bubbled into a solution of sodium hydroxide, the reaction forms sodium sulfide and water. How many grams of sodium sulfide are formed if 16.47 g of hydrogen sulfide is bubbled into a solution containing 25.22 g of sodium hydroxide, assuming the limiting reagent is completely consumed?
admin answers:
H2S + NaOH –> Na2S + H2O, balance the equation
H2S + 2NaOH –> Na2S + 2H2O
16.47g H2S = ?moles = 16.47g / 34g/mole = 0.51moles
25.22g NaOH = 25.22g / 40g/mole = 0.63 moles
from the balanced equation, 1 mole H2S yields 1 mole Na2S so you would yield 0.51 moles Na2S
2 moles NaOH yields 1 mole Na2S so you would yield 0.315 moles Na2S
NaOH is the limiting reactant
this would only yield 0.315 moles Na2S which is ?g 0.315moles x 78g/mole = 24.57g Na2S
Paul asks…
How does carbon sequestration using hydrogen sulfide work?
I assume this would take one heck of a lot of hydrogen sulfide. Hydrogen sulfide is quite toxic, so how safe would the process be? What would be the potential environmental side effects of the process? Isn’t H2S a significant greenhouse gas all by itself? How would we produce enough hydrogen sulfide to make a dent in global warming this way?
admin answers:
Isn’t it time we required universal Federal licensing for use of Alka Seltzer, Fizzies, and Pop Rocks? Background verification, two week cooling off period, fingerprinting, mandatory fizz locks. No gas release in excess of one liter. No automatic unloading – no motorized or wind-up Pez dispensors!
CO2 kills! Suffocation! GREENHOUSE EFFECT! Save our children!
Sandra asks…
How would you find the amount of hydrogen sulfide though a precipitate?
If I am trying to determine the exact volume of hydrogen sulfide gas in a closed container though means of precipitation, obviously I should draw a sample of the gas mixture, but with what chemical should I react the hydrogen sulfide with to produce a precipitate that can be gravimetrically analyzed?
admin answers:
Mercuric acetate, Hg(C2H3O2)2(aq) + H2S(g) ===> HgS(s) + 2HC2H3O2(aq). HgS is one of the most water insoluble substances known. The Ksp is about 10^-50.
