Answer: 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of
Explanation:
The balanced decomposition reaction is shown as
moles of
According to stoichiometry:
2 moles of gives = 3 moles of flourine gas
Thus 0.36 moles of gives =
of flourine gas
Using ideal gas equation :
P = pressure of gas = 1 atm ( at STP)
V = Volume of gas = ?
n = moles of gas = 0.54
R = gas constant = 0.0821 L atm/Kmol
T = temperature = 273 K ( at STP)
Putting the values we get :
Thus 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of
Answer:
1.90 atm
Explanation:
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
According to above equation, at constant Volume and number of moles, pressure is directly proportional to the temperature. So,
Given ,
P₁ = 1.51 atm
P₂ = ?
T₁ = 23 °C
T₂ = 100 °C ( boiling point of water )
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (23 + 273.15) K = 296.15 K
T₂ = (100 + 273.15) K = 373.15 K
Using above equation as:
<u>New Pressure = 1.90 atm</u>
