notka56 [123]

Answer:

The mass density will be doubled

Explanation:

  • Density is given by dividing the mass of a substance by its volume.
  • An increase in mass causes an increase in density and vice versa, while a  decrease in volume causes an increase in density and volume.
  • Therefore, when the volume is halved, then the density will be doubled if the mass is kept constant.
  • This has no effect on the number of moles as the mass is constant.

The ability of a material to burn (its flammability) is an indication of the materials reactivity with oxygen. Does the informat
Nataliya [291]

Answer:

Yes, this theory supports the inert nature of noble gases.

Explanation:

Noble gases already attain octet state stability, by having their outer shells completely filled with electrons. This makes them unable to take part in chemical reaction (by lose, gain or sharing of electrons).

Flammability occurs when matter burns through combination with oxygen, and changes to a different substance.

I hope this explanation is clear, let me know if I can be of further assistance.
