Phosphorus is a chemical element. So it existed long before man appeared on earth and is, therefore, definitely not man-made. However, because it is so reactive it is never found in its pure form on earth. Thus, any quantity of the pure substance must be made by us from one of the phosphorus compounds that occurs naturally.
Sodium hydroxide, also known as lye or caustic soda, is a synthetic compound that is industrially produced through the electrolysis of salt water. It is not found naturally in its pure form in the environment.
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
No, phosphorus is not used in the manufacturing of car tires. Car tires are typically made from rubber compounds, which may contain ingredients like natural rubber, synthetic rubber, carbon black, and various chemicals and oils.
i don't know is it man made or natural?
Phosphorus is a solid. There are various forms, allotropes of phosphorus:-White phosphorus consisting of P4 molecules - most familiar formRed phosphorus with chain structureViolet phosphorus with a complex layer structureBlack phosphorus a metallic looking substance with a layer structure
That is the correct spelling of "synthetic" (manmade by chemical synthesis).
Phosphorus is an element. It's natural.
Dacron is a manmade synthetic fiber, which is a type of polyester. It is not a natural fiber like cotton, wool, or silk. Dacron is known for its durability and resistance to wrinkles and stretching.
Wallpaper is manmade. It is typically made from a combination of paper, fabric, vinyl, or other synthetic materials, layered or coated with decorative designs or patterns.
Synthetic codeine is just codeine made in a lab by scientists, synthetic means fake which is unnatural which is man made so manmade codeine
"Synthetic" could be another word for something that does not occur naturally.
Establishments primarily engaged in manufacturing noncellulosic, or synthetic, fibers comprise the manmade organic fibers industry.
There is natural rubber, made from the latex of the rubber tree (Hevea brasiliensis).There are several manmade rubber compounds, including butyl rubber, neoprene, and nitrile rubber.
The foods that contain phosphorus are more likely to have more phosphorus if they are grown organically. This is due to organic practices that build up the soil with compost, non-synthetic fertilizers, etc. In addition, organic methods help to replenish micronutrients, which are needed for optimal health. Synthetic fertilizers are usually nitrogen, phosphate, and potassium, but lack macronutrients.
Sodium hydroxide, also known as lye or caustic soda, is a synthetic compound that is industrially produced through the electrolysis of salt water. It is not found naturally in its pure form in the environment.
Tires. During world war II there was a shortage of rubber and they started making tires out of synthetic rubber. Little did they know it was going to out perform what they were trying to replace and now we have better tires because of it.
Synthetic fabrics are produced from manmade substances, many of them petroleum based. The original elements are created in a lab by chemists. The word "synthetic" means artificial. Examples of synthetic fabrics are polyester, nylon, and acrylic. Natural fabrics come from plant or animal sources - examples are cotton, wool, linen, and silk.
