Equation: NH4HS(s) <=> NH3 (g) + H2S(g)
Kc = [NH3]eq[H2S]eq; where eq subscripts are used to indicate that those are the concentrations at equilibrium
Kc= 0.272 * 0.365 =0.09928
Carbon=10.0
Hydrogen=6.7
Oxygen=53.5
Next, divide by their atomic masses. The atomic masses of the elements are;
Carbon=12, Hydrogen=1, Oxygen=16
So that will be
Carbon=40/12=3.3
Hydrogen=6.7/1=6.7
Oxygen=53.5/16=3.3
Next, divide by the smallest number. The smallest number is 3.3
Carbon=3.3/3.3=1
Hydrogen=6.7/3.3=2
Oxygen=3.3/3.3=1
So the empirical formula will be
C₁H₂O₁ which is the same as CH₂O
To get the molecular formula;
(CH₂O)n=molecular mass
Now we need to find n
(CH₂O)n=60
Multiply the atomic masses of each by the subscript and add them all
C₁=12 x 1=12
H₂=1 x 2=2
O₁=1 x 16=16
(12+2+16)n=60
(30)n=60
Divide both sides by 30
therefore; n=60/30
n=2
Next, multiply CH₂O by 2
C=1 x 2=2
H₂=2 x 2=4
O=1 x 2=2
So you have the empirical formula to be C₂H₄O₂
Hope that helped. Have a nice day
Answer:
237 K
Explanation:
Given that,
Initial temperature, T₁ = 201⁰C = 474 K
Let P be the initial pressure. Upon cooling the gas, the pressure decreases by a factor of 2.0, while the volume and the amount of gas remain constant.
Final pressure = P/2
The relation between the pressure and temperature is as follows :
Put all the known values,
So, the final temperature of the gas is equal to 237 K.
For approximate results, divide by the bolded values
1 cubic centimeter / 1 = 1 milliliter
1 cubic centimeter / 16.387 = 0.06 cubic inches
1 cubic centimeter / 28317 = 3.5 cubic feet
1 cubic centimeter / 1000 = 0.001 liters
Hope this is what you were looking for. Let me know if there is another measurement you would like me to convert to :)
