Which of the following statements best describes the Propogation step of an addition polymerization reaction?
a)Step that ends the polymerization reaction by combination of two growing
chains into a single hydrocarbon chain.
b)Step in which monomer subunits are added to a growing polymer chain with
the loss of a water molecule
c)Step that begins the polymerization reaction with the use of heat and a
catalyst
d) Step in which monomer subunits are added to a growing polymer chain

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

i would say b

explanation:

but i think i would need more information than that
