What volume of ethylene gas at 293k and 102kpa must be compressed to yield 295m3 of ethylene gas at 808kpa and 585k

1170.43 m³

We are given;

We are required to find the new volume;

Therefore, the volume is 1170.43 m³

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
