What is the comversion factor used when converting mass to moles? A. 6.02 x10 particles = 1 mole

B. 22.4L = 1 mole

C. the answer is not listed

D. molar mass = 1 mole

6.02 x 10^23 particles = 1 mole

Explanation:

If A. has 10 to the power of 23 then that is the answer, but if it does not, then the answer is C.

- 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
