Why are mixtures of gases, such as argon and helium, much more likely to form an ideal solution than other combinations such as solids and liquids? a. gases are more polar than liquid solvents. b. when gases are mixed, the resulting solution has significantly different properties from the original components c. the gases experience little or no interaction between molecules or atoms. d. none of the above.

When gases are mixed, the resulting solution has significantly different properties from the original components

Explanation:

- 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
