Which gas sample contains the most molecules ?
Answer:
CO2
Explanation:
(a) CO2; according to Avogadro's Hypothesis, they all contain the same number of particles, therefore, the heaviest molecule, CO2 (molar mass = 44), will have the greatest mass. (b) all the same; at the same temperature all gases have the same kinetic energy.

Learning Task No. 3: Write a short paragraph regarding the differences between
saturated and unsaturated solutions.
Type of Solution
Explanations about the differences of
the two solutions
Saturated solution
Unsaturated solution
Answer:
See explanation
Explanation:
A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.
