In a high-pressure separation process, a gas having amasscomposition of 50 wt% benzene, 30 wt % toluene, and 20 wt % xylene is fed into the process at the rate of 483 m3/hr at 607 k and 26.8 atm. one exit stream is a vapor containing 91.2 mole % benzene, 7.2 mole % toluene, and 1.6 mole % xylene. a second exit stream is a liquid containing 6.0wt % benzene, 9.0wt % toluene, and 85.0wt % xylene. what is the composition(mas fractions)of the third exit stream if it is liquid flowing at the rate of 9800 kg/hr, and the ratio of the benzene to the xylene in the stream is 3 kg benzene to 2 kg xylene?

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

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.
