Before opening or disposing of appliances like refrigerators, air conditioners, and freezers, any refrigerants used within them, such as R-134a, R-410A, or R-22, must be recovered. This process is essential to prevent the release of harmful substances into the environment, as many refrigerants can contribute to ozone depletion or have high global warming potential. Proper recovery should be conducted by certified technicians using appropriate recovery equipment in compliance with local regulations.

What the differences between ring-opening polymerization and ring-opening metathesis polymerization?

Ring-opening polymerization involves the opening of cyclic monomers with formation of linear polymer chains, while ring-opening metathesis polymerization involves the redistribution of double bonds in cyclic monomers to form a polymer chain. Ring-opening polymerization can use a variety of monomers, whereas ring-opening metathesis polymerization is typically limited to cyclic olefins. Additionally, ring-opening polymerization relies on nucleophilic or electrophilic initiators, while ring-opening metathesis polymerization relies on metal catalysts.

Which refrigerants must be recovered before opening or disposing of appliance?

Older appliances and automobiles used Freon (R-12) as a refrigerant. In the many years after it's introduction - scientists discovered that Freon is actually a greenhouse gas. It's a Hydrocarbon responsible for destroying the earths atmosphere.However, this is not limited to just R-12, but R-12 is the main gas that needs to be disposed of. All refrigerants should be properly withdrawn from appliances and automobiles so that it may be recycled or contained. This prevents unwanted chemical reactions at landfills (Imagine if someone threw away a sodium block that came into contact with rain water - boom!) and to protect the environment if future Scientists discover the current refrigerant we use is harmful.

Do you apply theatre makeup or latex first?

I'm failing to see any real point in applying makeup you will then cover up with latex anyway. Under some unusual circumstances you might want to apply makeup prior to adding a latex appliance (if, for example, the skin beneath will be able to be seen through an opening in the appliance), but normally the makeup will be the finish.
