Answer:
Water absorption can occur as soon as 5 minutes after ingestion and peaks around 20 minutes after ingestion.
Explanation:
The electrons are transferred from potassium to sulphur, in this reaction, potassium is being oxidised and sulphur is being reduced. Two potassium atoms each lose one electron forming K+ ions. Sulphur gains two electrons forming S2-/2- ions. The resultant formula will be: K2S, bonding in this compound is ionic.
Answer:
14 moles
Explanation:
For an Ideal gas,
PV = nRT...................... Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = Molar gas constant.
make n the subject of the equation
n = PV/RT.................. Equation 2
Given: P = 14.297 atm, V = 22.9 L = 22.9 dm³, T = 12 °C = (12+273) K = 285 K.
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (14.297×22.9)/(285×0.082)
n = 327.4013/23.37
n = 14.009
n ≈ 14 moles
Answer:
Solutions with low pH have a sour taste.
Explanation:
Answer:
.46 moles
Explanation:
PV = n RT make sure you use the correct R = 8.31446 L-kPa/(K-mol)
36 * 38 = n * 8.31446 * (273.15 + 82)
n = .463 moles
