Answer:
The maximum mass of sodium sulfide that could be produced is 35.26 grams.
Explanation:
Moles of sodium sulfate =
Moles of carbon =
According to reaction, 1 mole of sodium sulfate reacts with 4 moles of carbon.
Then 0.6514 moles of sodium sulfate will react with:
of carbon.
2.6056 moles of carbon > 1.8083 mol of carbon (given)
As we can see that moles of sodium sulfate are in excess ,so, the amount of sodium sulfide will depend upon moles of carbon.
According to reaction, 4 mole of carbon gives with 1 moles of sodium sulfide.
Then 1.8083 moles of carbon will give :
of sodium sulfide.
Mass of 0.4521 moles of sodium sulfide:
0.4521 mol × 78 g/mol = 35.26 g
The maximum mass of sodium sulfide that could be produced is 35.26 grams.
Meteors: A small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a steak of light.
Meteorites: A meteor that survives it passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel.<span />
The first dissociation for H2X:
H2X +H2O ↔ HX + H3O
initial 0.15 0 0
change -X +X +X
at equlibrium 0.15-X X X
because Ka1 is small we can assume neglect x in H2X concentration
Ka1 = [HX][H3O]/[H2X]
4.5x10^-6 =( X )(X) / (0.15)
X = √(4.5x10^-6*0.15)
∴X = 8.2 x 10-4 m
∴[HX] & [H3O] = 8.2x10^-4
the second dissociation of H2X
HX + H2O↔ X^2 + H3O
8.2x10^-4 Y 8.2x10^-4
Ka2 for Hx = 1.2x10^-11
Ka2 = [X2][H3O]/[HX]
1.2x10^-11= y (8.2x10^-4)*(8.2x10^-4)
∴y = 1.78x10^-5
∴[X^2] = 1.78x10^-5 m
