Complete this sentence. the solubility of a sample will when the size of the sample increases.

a) stays the same
b) decrease
c) increase
d) be unable to be undetermined

Option (B) is the correct answer.

Explanation:

The solubility of a sample will decrease when the size of the sample increases.

On increasing the size of sample, the surface area will increase which will result in large number of molecules. Therefore, the amount of solute particles will increase whereas the amount of solvent is the same.

Hence, to dissolve these large number of molecules more solvent is required that is the solubility will decrease.

Thus, we can conclude that larger is the size of molecule, less will be its solubility.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
