2. Peter Pill works at "Drugs-R-Us," a pharmaceutical company. He receives a shipment of 456.90 kg of aspirin, however, the proper dosage is in milligrams.
a. How many milligrams is in this shipment?
b. If a daily dose of this drug is 5.00 mg, how many doses are in this shipment?

- 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

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
