Answer:
See the explanation.
Explanation:
Hydrocarbons on combustion give carbon dioxide and water.
Hydrocarbons contain all kinds of saturated and unsaturated ones.
Alkanes on reaction with oxygen gives carbon dioxide and water.
Alkenes on reaction with oxygen gives carbon dioxide and water.
Alkynes on reaction with oxygen gives carbon dioxide and water.
Answer:
321.6 g/Mol
Explanation:
mass of solvent in kilograms = 90g/1000 = 0.09 Kg
Given that;
ΔTf = Kf . m . i
Where;
Kf = freezing point constant = 4.25 °C/Kg mol
m = molality of the solution
i = Van't Hoff factor = 1 (since the substance is molecular)
ΔTf = freezing point of pure solvent - freezing point of solution
freezing point of pure solvent = 3 °C
ΔTf = 3 °C - 2.1 °C
ΔTf = 0.9 °C
0.9= 4.25 * 6.13/M/0.09 * 1
0.9= 26.0525/M * 1/0.09
0.9 = 26.0525/0.09 M
0.9 * 0.09M = 26.0525
M = 26.0525/0.9 * 0.09
M= 321.6 g/Mol
Saturated.
An unsaturated solution is a solution where more solute can still be added.
Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
