85. Compare a mole of Ag-108 and a mole of Pt-195 using atoms, protons, electrons, and neutrons.

Explanation:

1 mol of an atom (irregardless of the element) contains the Avogadro's number of atoms. This is given as;

1 mol = 6.022 * 10^23 atoms

For a neutral atom;

NUmber of protons = Number of electrons

The relationship between proton and neutron is given as;

Mass Number = Protons + Neutrons

Ag-108

Atoms =  6.022 * 10^23 atoms

Protons = Atomic Number = 47

Electrons = 47

Neutrons = Mass Number - Protons = 108 - 47 = 61

Pt-195

Atoms =  6.022 * 10^23 atoms

Protons = Atomic Number = 78

Electrons = 78

Neutrons = Mass Number - Protons = 195 - 78 = 117

true

hope that

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
