Answer : The ions present in the solution of are
and
in aqueous state.
Explanation :
When is in aqueous solution then they dissociates into their ions.
The reaction in aqueous medium is,
The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.
Therefore, the ions present in solution of are
and [tex]CO^{2-}_3[tex] in aqueous state.
Answer: The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = ?
V= Volume of the gas =
T= Temperature of the gas = 10°C = 373 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 0.25 +0.034 = 0.284 moles
= mole fraction of oxygen=
,
=mole fraction of carbon dioxide=
partial pressure of oxygen =
partial pressure of carbon dioxide=
The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
