Given:
K = 0.71 = Kp
The reaction of sulphur with oxygen is
S(s) + O2(g) ---> SO2(g)
initial Pressure 6.90 0
Change -x +x
Equilibrium 6.90-x x
Kp = pSO2 / pO2 = 0.71 = x / (6.90-x)
4.899 - 0.71x = x
4.899 = 1.71x
x = 2.86 atm = pressure of SO2 formed
temperature = 950 C = 950 + 273.15 K = 1223.15 K
Volume = 50 L
Let us calculate moles of SO2 formed using ideal gas equation as
PV = nRT
R = gas constant = 0.0821 L atm / mol K
putting other values
n = PV / RT = 2.86 X 50 / 1223.15 X 0.0821 = 1.42 moles
Moles of Sulphur required = 1.42 moles
Mass of sulphur required or consumed = moles X atomic mass of sulphur
mass of S = 1.42 X 32 = 45.57 grams or 0.04557 Kg of sulphur
<span>(15.0 g) / (150.0 g) x (100 g) = 10.0 g/100 g H2O </span>
Answer:
the mass number is 40 g/mole
Given NH4Cl + NaClO3 =
In order to figure out which salts are soluble in water, and which ones of their products are soluble in water:
we will have the following Molecular products :
• NH4Cl + NaClO3 = NaCl + NH4ClO3,
( both salts are soluble in water)
Natural sources include decomposition,ocean release and respiration.
Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal,oil and natural gas.
