Volume of carbon dioxide absorbed = 33.6 L ≈ 34 L
Explanation:
We have the following chemical reaction:
CO₂ (g) + 2 LiOH (s) → Li₂CO₃ (s) + H₂O (l)
Now we devise the following reasoning:
if 1 mole of carbon dioxide reacts with 2 moles of lithium hydroxide
then X moles of carbon dioxide reacts with 3 moles of lithium hydroxide
X = (1 × 3) / 2 = 3/2 moles of carbon dioxide
And we calculate the volume of carbon dioxide using the following formula:
number of moles = volume / 22.4
volume = number of moles × 22.4
note: units for 22.4 are "L / mole"
volume of carbon dioxide = (3/2) × 22.4 = 33.6 L ≈ 34 L

Answer;
Fractional distillation
Explanation;
-Fractional distillation is one of the method that is used to separate mixtures. It is used for the separation of miscible liquids, for example water and alcohol.
-Fractional distillation is a distillation method that is used to separate liquids that dissolve in each other. It involves separating the components of a mixture by repeated distillations and condensations.
-The components in the mixture being separated by this method normally have different but close boiling points. For example a mixture of alcohol and water, they have different but close boiling points, thus during distillation alcohol condenses out as the first fraction followed by water.
T = 2500 + 100c
where t is his total monthly salary and c is the number of cars he sold in a given month
Answer:
Here's what I get
Explanation:
1. Nickel sulfate
base + acid ⟶ salt + water
NiSO₄ is a salt of the base Ni(OH)₂ and the acid sulfuric acid.
Hydroxides of transition metals are insoluble; most sulfates are soluble.
2. Carbonate + acid
Most carbonates are insoluble.
They react with acids to form carbonic acid (H₂CO₃), which decomposes into water and carbon dioxide.
The osmotic pressure of a solution made from 12.5 g of CaCl2 in enough water to make 500 mL, if CaCl2 is 78.5% dissociated at 30oC is 167.087 atm
<h3>
Define osmotic pressure:-</h3>
Osmotic pressure and osmosis are connected. Osmosis is the passage of a solvent through a semipermeable membrane into a solution. The pressure that halts the osmosis process is known as osmotic pressure. Osmotic pressure is a collective attribute of material because its value is determined by the solute's concentration rather than its chemical composition.
The formula used to calculate Osmotic Pressure is:-
π = M x R x T x i
Where;
π =osmotic pressure (in atm)
M=molar concentration (in mol/L)
=(given mass/molar mass)/volume=(12.5g /111.0)/(500/1000)
=0.224 mol/L
R=Universal gas constant (0.08206 L.atm/mol.K)
T=absolute temperature (in K) = 30.C + 273 = 303 K
i= van't Hoff factor of solute =3
using the formula and substituting values;
π=0.224 x 0.08206 x 303 x 3
= 167.087 atm
The osmotic pressure is 167.087 atm
