Question

Noble gases are inert because

  1. They are highly reactive
  2. They are unreactive
  3. They are noble
  4. They have 8 electrons in their outermost energy level

hintHint:

A gas can be classified as noble gas on the basis of its electronic configuration.

The correct answer is: They have 8 electrons in their outermost energy level


    • Noble gases are inert because They have 8 electrons in their outermost energy level.
    • Noble have complete octets and are stable they do not want any electrons or want to donate any.

    ____ 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).
