Apolymer contains monomers linked by
a. ) ionic bonds
b. ) covalent bonds
c. ) polyatomic ions
d. ) hydrogen bonds

The correct answer is

B) Covalent Bonds.

Explanation:

A chemical reaction bonding monomers commonly to make a polymer is called polymerization. Some polymers are physical and created by organisms. Proteins have polypeptide molecules, which are natural polymers made from various amino acid monomer units. A particular polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. Covalent bonds hold the atoms in the polymer molecules together and formed bonds then hold groups of polymer chains collectively to form the polymeric material.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
