Molar mass Mg = 24.3 g/mol
1 mole mg ------------ 24.3 g
?? moles mg --------- 4.75 g
4.75 x 1 / 24.3 => 0.195 moles of Mg
hope this helps!

Thermal energy found when internal energy is transferred.
1) KCl
Potassium Chloride is an ionic bond because it exists between a metal and a nonmetal. The Potassium ion is a cation, carrying a +1 charge; the Chlorine is an anion, carrying a -1 charge.
Because the size of atoms increase as you move down the periodic table.
