Question
Gases that exhibit stability and low reaction rates are called ______________.
- Halogen gases
- Noble gases
- Boron gases
- Carbon gases
Hint:
Gases that exhibit stability and low reaction rates are called Noble gases
The correct answer is: Noble gases
They are stable because the outer shell of the noble gases is perfect, they are very stable, with no tendency to form chemical bonds, and little tendency to accept or lose electrons. Under standard conditions, all members of the noble gas group behave similarly.
There are six gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

____ 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.
