Answer:

Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.

A sample of nitrogen gas has a volume of 237mL at 9.86atm. What is the new
MrRa [10]

Answer:

The new  volume of the gas when the pressure is changed to 2.84 atm is 822.82 mL.

Explanation:

Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure." That is, if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

or

P * V = k

Assuming that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment, by varying the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1*V1=  P2*V2

In this case:

  • P1= 9.86 atm
  • V1= 237 mL
  • P2= 2.84 atm
  • V2=?

Replacing:

9.86 atm* 237 mL= 2.84 atm*V2

and solving you get:

V2=\frac{9.86 atm* 237 mL}{2.84 atm}

V2= 822.82 mL

<u><em>The new  volume of the gas when the pressure is changed to 2.84 atm is 822.82 mL.</em></u>
