When running a spectrum of a neat liquid, what are problems that may arise when: a. using a low-viscosity liquid? b. using a viscous liquid?

Answer 1) : Weak peaks

Explanation : When running a spectrum of a neat liquid, the problems that may arise using a low-viscosity liquid there will be weak peaks obtained and it will be difficult to interpret them. As there will be very thin path length between the salt plates to obtain the spectrum. The quality of the peaks will be low.

Answer 2) : Strong peaks

Explanation : When running a spectrum of a neat liquid, while using a viscous liquid the obtained peaks will be strong peaks. As the viscous liquid will enable to form a thick layer between the salt plates which will produce strong, intense and sharp peaks. This will be high resolved and clear peaks on the spectrum.

- 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
