What is the IV Michael is the branch manager at
a little-known regional paper
supplier. He wants to see if music
in the break room can make his
employees more productive.
Despite HR objections, he plays a
different genre of music each
week--classical music, rap, rock,
and pop. At the end of the month,
he analyzes the numbers and sees
no significant differences.

- 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

the ratio of the conjugate base to the acid required to attain the desired ph.
