What effect does supercritical mass have on a nuclear reaction? the reaction rate increases. the reaction produces less energy. the reaction involves increased fusion. the reaction produces fewer neutrons.

The correct answer is "The reaction rate increases."

Explanation:

Supercritical mass is the mass of nuclear reactor fuel which is more than sufficient to sustain a nuclear chain reaction. At critical mass there is a stable or slow nuclear reaction. However, at supercritical mass such as in a nuclear bomb there is exponentially increasing number of nuclear fission reactions occurring in quick succession.

- 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
