Match the following definition to the type of solution it describes.

unsaturated solution
saturated solution
supersaturated solution

a.
the amount of solute dissolved is less that the maximum amount the solution can hold.
b.
the amount of solute dissolved is the maximum amount the solution can hold.
c.
the amount of solute dissolved is more than the usual maximum amount.

The following definition to the type of solution it describes are

unsaturated solution: A. The amount of solute dissolved is less that the maximum amount the solution can hold.
saturated solution: B. The amount of solute dissolved is the maximum amount the solution can hold.

supersaturated solution: C. The amount of solute dissolved is more than the usual maximum amount.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
