i believe from experience that by law,every manufacturer of any product, especially with any health or safety concerns,is required to supply by request,a Material Safety Data Sheet(MSDS)listing ingredients,chemical make-up,toxicity,safe handling,cautions,warnings,treatment for exposure,etc.,from spray paint to soap to metal to wood to plastics to make-up to.............Generally such records are required to be kept by employers, doctors, dentists,labs,etc. Knowing this,and one of my ferrets fondness for AJAX Liquid Soap,i searched for the product online,then typed in MSDS for,and there it was.
You first produce methacrylic acid. Once you're there, you esterify it to methyl methacrylate monomer. Polymerizing the monomer produces polymethyl methacrylate, which is the chemical name of acrylic plastic. Over 8 billion kilograms of acrylic were sold in 2015, so there are a lot of companies making it and quite a few different processes.
Yes, because several chemical reactions can occur.
Baking a cake is a chemical change because the baking powder or soda (whichever one) undergoes a chemical reaction. you can tell because of the bumps or air bubbles. Not only that, but the chemical change is irreversible, you put the ingredients that make up the cake together and you can't change them back. The ingredients don't go back to their original form. You can tell it's a chemical change becaue of the heat, rising, and odor.
it is both the heating of the glue mixture is chemical while the lumpiness and the color and it becoming more of a liquid is physical
It would depend on the soup and its ingredients. A vegetable soup will have solid ingredients making it a mixture. It can have fats and protein making it a suspension, and it will also have ingredients that are dissolved in the water making it also a solution.
Who has a reputation for making good fitting dentures?
No, the making of alfredo sauce is simply the combining of elements/ingredients. No chemical change occurs.
Because when you bake a cake, you cant take the ingredients back. And when you bake it, the chemicals rise, making it a Chemical Change.

A denture mold is part of the process in making new dentures. dentures are fabricated in stages: A mold or impression is taken of the anatomical structures in the mouth. The denture teeth are set in a wax material that is stable at mouth temperature, this allows the client to see the cosmetics of the denture and the clinician to check the bite. Once the decision has been made that everything is fine, that wax denture is then put into a flask with plaster. Once the plaster has hardened, the flask is placed into hot water which softens the wax, the flask is then opened and all the wax is removed. You then have a mould into which the acrylic can be placed. So the acrylic replaces the wax component and after processing the acrylic becomes hard. So the mold or mould could be either a term for the impression or a term for the flasking stage when you are making a mold or mold into which the acrylic would be placed to make the denture. We also use the term mold or mould in dentistry to describe the particular shape of denture teeth, teeth come in all shapes and sizes. The dentures themselves are the finished article worn by the client. If anyone has any questions on dentures they can email them to me stevej@mybrilliantsmile.com i am a registered dental professional who does the clinical work as well as the laboratory work for denture clients

Yes, the FDA does regulate dentures. Dentures are classified as medical devices and therefore fall under the FDA's jurisdiction. The FDA sets standards and regulations for the manufacturing, labeling, and marketing of dentures to ensure their safety and effectiveness.
Because of the amount of specialty measuring involved in making a partial denture it usually costs signifigantly more than full dentures. They take more skill to make.
