Question
_________ is used in dressing wounds.
- Chlorine
- Antiseptic
- Tincture iodine
- Aluminum
Hint:
It has 2%-7% of an element.
The correct answer is: Tincture iodine
- Iodine tincture, iodine tincture, or weak iodine solution is a preservative.
- It usually consists of 2-7% elemental iodine, along with potassium iodide or sodium iodide dissolved in a mixture of water and ethanol. Tincture solutions are characterized by the presence of alcohol in them. It is an over-the-counter product that is used to treat minor bacterial skin infections and disinfect wounds. This product is available in a disinfectant form and is currently not covered by Medicare.

____ is the synthetic fiber used to make parachutes.
The correct option is c)Nylon.
Nylon threads are very strong and can withstand high loads. As such, it is used to make parachutes and ropes for climbing. Nylon fibers are strong, elastic and shiny. It is easy to wash, dries quickly even after washing, and does not lose its shape. These properties make it ideal for making parachutes and raincoats.

Select the correct R principle for the statement. “To use something again that you would normally throw away.”
The correct option is b)Reuse.
Reuse is the act or practice of using an item, whether for its original purpose or to perform some other function. This should be distinguished from recycling, which dismantles used items to produce raw materials for manufacturing new products.

Ester is used in repeating units in the making of polyester. Choose true or false.
The statement is true.
- Polyester is a man-made or synthetic fiber made up of repeating units of chemicals called esters.
- Esters are sweet-smelling compounds composed primarily of carbon, hydrogen, and oxygen.
- The most commonly used polyester formula is: As an ester, it is made from the acid benzene-1,4-dicarboxylic acid (terephthalic acid) and the alcohol ethane-1,2-diol.
- It is better known by the mundane name of polyethylene terephthalate (PET).

The correct option is b)Acrylic.
- Polyester is a synthetic fiber obtained from coal or petroleum.
- Polyester is durable but breathable and not designed to absorb liquids.
- Acrylic fibers are made using acrylonitrile or vinyl cyanide polymers.
- Acrylic is often considered an imitation of wool because it retains heat.

Select the year in which nylon was made.
The correct option is a)1931.
Nylon, a synthetic plastic material composed of polyamides of high molecular weight, usually but not always manufactured as fibers. In the 1930s he founded the E.I. du Pont de Nemours & Company.
Nylons are a family of materials called polyamides, made by reacting carbon-based chemicals found in coal and petroleum in a heated, high-pressure environment. This chemical reaction, known as condensation polymerization, forms large polymers in the form of nylon films.

Synthetic fibers do not absorb much
The correct option is c)Water.
Synthetic fibers absorb less water than natural fibers because there are no voids between each fiber. Because water does not penetrate the individual fibers of this fabric, it dries quickly. Hydrophilic fibers readily absorb water without causing discomfort to the wearer, whereas hydrophobic fibers are where the fibers do not absorb water.
