Answer:
204.8 K
Explanation:
We use the ideal gas equation:
PV = nRT
where R is the gas constant (0.082 L.atm/K.mol).
We have the following data:
n= 4 moles
P = 5.6 atm
V = 12 L
So, we introduce the data in the ideal gas equation to calculate the temperature (T):
T = PV/nR = (5.6 atm x 12 L)/(4 mol x 0.082 L.atm/K.mol) = 204.8 K ≅ -68 °C
Answer:
P1 = 2.5ATM
Explanation:
V1 = 28L
T1 = 45°C = (45 + 273.15)K = 318.15K
V2 = 34L
T2 = 35°C = (35 + 273.15)K = 308.15K
P1 = ?
P2 = 2ATM
applying combined gas equation,
P1V1 / T1 = P2V2 / T2
P1*V1*T2 = P2*V2*T1
Solving for P1
P1 = P2*V2*T1 / V1*T2
P1 = (2.0 * 34 * 318.15) / (28 * 308.15)
P1 = 21634.2 / 8628.2
P1 = 2.5ATM
The initial pressure was 2.5ATM
Answer : The volume of the resulting solution will be 0.4999 L.
Explanation : As the two molar concentration of the
solution are given and one of the volume concentration needs to be found.
So, according to the formula :-
And here if we consider
as 0.1718 L moles and
as 0.3556 moles then we need to find
as
is given as 0.1222 moles.
Hence on solving the formula we get,
= (0.1718 X 0.3556) / 0.1222 = 0.4999 L
The dissociation of cadmium chloride is as follows: CdCl₂(s) → Cd⁺²(aq) + 2Cl⁻(aq)
<h3>What is dissociation?</h3>
Dissociation is the process by which a compound body breaks up into simpler constituents; said particularly of the action of heat on gaseous or volatile substances.
It is a chemical reaction in which a compound breaks apart into two or more components. The general formula for a dissociation reaction follows the form:
AB → A + B
According to this question, cadmium chloride undergoes dissociation into cadmium and chlorine ions as follows:
CdCl₂(s) → Cd⁺²(aq) + 2Cl⁻(aq)
