Asample of gas has a volume of 5.58 l at a pressure of 715 mm hg. what is the volume of the gas when the pressure of the gas is increased to 755 mm hg?

The  volume  of the  gas  when  the  pressure  of  the  gas  increases  to  755mm  hg  is   calculated  as  follows

  by  use  of  boyles  law  formula  that  P1v1=P2V2
V2=  P1V1/P2
V1=5.58  L
P1=  715  mm  hg
P2=755  mm  hg
V2  is  therefore=   ( 715  mm  hg  x  5.58  L) /755  mm hg=  5.28 L

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.

Nonmetal are moldable and easily shaped
