What is the process in which alkene monomers join end-to-end, or add on to one another, to form chains?
a. daisy polymerization
c. substitution polymerization
b. addition polymerization
d. doldrum polymerization

b. Addition polymerization

Explanation:

Polymerization is a chemical reaction in which small units called as monomers combine together to result into bigger molecules called as polymers.

Condensation polymerization : A chemical reaction in which small units called as monomers are joined to form a bigger molecule called as polymer and small by products are also formed along with the polymer.  Example: Nylon-6

Addition polymerization : A chemical reaction in which small units called as monomers are joined end to end to form a bigger molecule called as polymer.  Example: Polythene

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
