Answer:
223 L
Explanation:
Step 1: Write the balanced equation.
2 LiOH + CO₂ = Li₂CO₃ + H₂O
Step 2: Calculate the moles corresponding to 440 g of LiOH
The molar mass of LiOH is 23.95 g/mol.
440 g × (1 mol/23.95 g) = 18.4 mol
Step 3: Calculate the moles of CO₂ that react with 18.4 moles of LiOH
The molar ratio of LiOH to CO₂ is 2:1. The reacting moles of CO₂ are 1/2 × 18.4 mol = 9.20 mol.
Step 4: Convert 20°C to Kelvin
K = °C + 273.15 = 20 + 273.15 = 293 K
Step 5: Convert 753 torr to atm
753 torr × (1 atm/760 torr) = 0.991 atm
Step 6: Calculate the volume of CO₂
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 9.20 mol × (0.0821 atm.L/mol.K) × 293 K / 0.991 atm
V = 223 L
We are given with
V = 12L
T = 298 K
P = 1000 kPa
We are asked to get the number of moles, n
We can solve this using the ideal gas law
PV = nRT
n = PV / RT
Simply substitute the values and use the appropriate value for R.
An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions.
<h3>What is the difference between ionic equation and net ionic equation?</h3>
- A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.
- A molecular formula has two or more atoms bonded together, whereas a chemical formula can only refer to one atom. They are both elements, and their chemical symbols are unchanged.
- An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions. It is similar to a molecular equation in that it expresses compounds as molecules.
3FeSO4(aq) + 2K3PO4(aq) = Fe3(PO4)2(s) + 3K2SO4(aq)
ionic equation : 3Fe(2+)(aq) + 3SO4(2-)(aq)+ 6Na(+)(aq) + 2PO4 (3-) (aq) → Fe3(PO4)2(s)+ 6Na(+) + 3SO4(2-)(aq)
net ionic equation: 3Fe(2+)(aq) + 2PO4 (3-)(aq) → Fe3(PO4)2(s)
K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s)
net ionic equation for K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s).
2HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2
ionic equation : CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O()
