Answer:
CCl₄, because it is the heaviest compound.
Explanation:
When a liquid is in a closed container, evaporation occurs, in what the molecules with the highest kinetic energy can scape of the liquid. The vapor that was formed does pressure on the liquid that remains, and when both phases stay in equilibrium the pressure is called vapor pressure.
We can notice that the vapor pressure is a measure of the volatility of a liquid. Substances with higher vapor pressure are more volatile. The volatility, however, depends on the nature of the forces in the compound and on the molar mass of it.
For the substances given, they are all covalent compounds and have dipole-induced-dipole-induced bonds between the molecules (because they are nonpolar). So, the lowest vapor pressure is in the heaviest compound, which is the most substituted: CCl₄.
D. Ca (oh)2 (calcium hydroxide)
Mass and volume are two units used to measure objects. Mass- the amount of matter an object contains and volume- how much space it takes up
Answer:
the sun is the ultimate source of energy for everything in the food web
Answer: Option (1) is the correct answer.
Explanation:
Melting point is defined as the point at which a solid state of a substance starts to melt and it converts into liquid state.
Also, it is known that more is the number of linear carbon atoms attached to each other, more is the melting point of a substance. Whereas more is the branching present in a compound least will be its melting point.
For example, has only 5 carbon atoms attached to carboxylic acid group. Whereas has 9 carbon atoms attached to carboxylic acid group.
Therefore, compound will have low melting point.
Thus, we can conclude that out of the given options, fatty acid has the lowest melting point.
