B. They decrease. As more we use the sources of nature, the less is left.
Hello!
The type of polymer that is made by bonding an alkene to one or more alkanes or alkenes is called addition polymer
Addition polymers are those whose polymerization reaction doesn't produce low molecular mass compounds but the bonding of molecules one after the other. Such a reaction implies that there is a rupture in the bonding between monomers (the building blocks of the polymer) to allow the formation of a chain.
Bonding an alkene to one or more alkanes or alkenes is an example of an addition polymerization.
Have a nice day!
Well part of the water cycle is evaporation which come from heat which you get from the sun. When the water evaporates it goes into clouds so then it can rain.
Hope this Helps
Increased atmospheric carbon dioxide will diffuse to the ocean water (since normally, there is lower concentration of dissolved carbon dioxide in the ocean water). The dissolved carbon dioxide takes into the form of carbonic acid thereby increasing acidity of ocean water. More often than not, the acidification of ocean water leads to detrimental results especially in marine organisms that are pH sensitive such as coral reefs and many invertebrates.
