Is acrylic a synthetic fiber?
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. To be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. The Dupont Corporation created the first acrylic fibers in 1941 and trademarked them under the name Orlon
What happens to ethene makes polyethene?
It is made by a process called polymerization, this is where they take lots of monomers (in this case ethane) and combine them together using an addition reaction. This is only possible in monomer where there is a double bond as to add them the double bond has to break for there to be enough room on the carbon for the new monomer. this process is done millions of times and is finally makes polythene which is used to make bin liners and poly bags.
What is the manufacture process of nylon fibre?
Nylon is created by combining chemicals that are extracted from raw materials such as coal. This was first produced by DuPont Company between the 1920s and 1930s.
Why are synthetic materials made?
Because you can design a synthetic polymer to exactly meet your needs. You can modify a natural polymer sometimes if it's not what you need, but at that point is it really a "natural" polymer? Take cellulose--a perfectly serviceable natural polymer, they build millions of homes every year out of it. But what if you need a polymer you can see through? Cellulose won't work for you there unless you dissolve it in acetic acid (cellulose acetate) or nitric acid (cellulose nitrate). By the time you're done, you have a polymer that's no longer really "natural."
What process take place in the mitochondria?
It is called respiration.It generates energy for the cellRespiration is taken place. Respiration is the energy generating process
Describe the formation of polyethene as an example of additional polymerisation of monomer units?
Alkene such as ethene contain c=c double bond.Hence these molecules can take part in addition reaction where the double bond is broken and other atoms attach to the carbon across the double bond to form large molecule such as polyethene. Here the ethene is the monomer and polyethene the addition polymer which is formed under high pressure, heat and by using a catalyst.
Is stearic acid a monomer or polymer?
It wouldn't generally be considered as either a polymer or a monomer. Stearic acid is a long chain (18 carbons long) carboxylic acid (sometimes known as "fatty acid"). Therefore its molecules are not sufficiently long to be considered a polymer, and there is no functionality along the carbon chain to enable polymerisation to take place, therefore it would not be classed as a monomer either. Small molecules are only referred to as "monomers" in the context of their ability to link together with many other similar molecules to form polymers. Note that it is possible to create polymers using certain carboxylic acids, but they need to have two carboxyl groups (reaction of dicarboxylic acids with diols creates polyesters by a condensation reaction). Stearic acid only contains one carboxyl group.

How many units does it take to make origami fireworks?
It takes 12.
How do you make a polymer clay lightswitch cover?
take a block of clay and slice it thin then in the middle cut a rectangle then on the top and bottom make a hole for the screws. then bake

8
How many unit cubes would it take to make a model of a rectangular prism that is 6 units long x4 units wide x2 units high?
48 unit cubes
Combining a molecule of glucose with a molecule of fructose to make a larger molecule of sucrose is an example of?
I hope this is what you are looking for! When you combine two monomers (an individual building block, e.g. a molecule of fructose) to make a polymer (the linked chain made of the monomers) you go through a process called dehydration reaction, or dehydration synthesis. In dehydration synthesis one molecule of water is taken out from the monomers which combines them together. An unlinked monomer (e.g. the molecule of fructose and glucose) will have a hydroxyl group at one end (-OH) and a hydrogen atom at the other end (-H). When you take out the water (H20) you form a covalent bond between the end of one monomer, and the beginning of the next - linking the two monomers
How do you stop polymer clay from picking up bits of dirt and lint?
To stop the polymer clay from picking up dirt and lint is to get the clay and then take the link and dirt out of it. and then that's how we can stop the link and dirt of getting into the polymer clay.
How to make water proof polyvinyl acetate?
Polyvinyl Acetate (PVAC) IS water proof. Any polyvinyl acetate (PVAC) is made via polymorization of vinyl acetate monomer. The raw material (pvac monomer) liquid is pumped into the reaction tank for polymerization. The reaction is done under normal temperature. Normally it will take hours.
What is the difference between simple and complex sugar?
Carbohydrates are one of the four macromolecules of life- Lipids, Proteins, Nucleic Acids, and Carbohydrates. These molecules have simple forms called monomers and more complex forms called polymers. Starches are a polymer of carbohydrates or a complex form of carbohydrates. A monomer of carbohydrates is a monosaccharide or simple sugar. To make a polymer there needs to be more than one monomer together. An example is the monomer glucose. When you have two glucose molecules bonded together you get the polymer maltose. Monomers glucose and fructose bonded together makes polymer sucrose. These examples are disacchrides. Di- meaning two sacchrides- meaning sugar. Polysacchrides Poly- meaning many and sacchrides- meaning sugar. Starch is a polysacchride, so it has many monomers bonded together. Therefore a complex carbohydrate or a polymer of a carbohydrate.
How many square units are an office that is 13 units by 9 units?
You take the product of the office's dimensions: 13 units x 9 units = 117 square units. The answer is 117 square units.
