Answer:  This is only a guess:  The "following chemical formula:      " doesn't appear on my screen.  But since you mentioned Mg and Cl, I would guess MgCl2

Explanation:  Mr loses 2 electrons while each Cl gains one each:  Two chlorines for every 1 magnesium.

How many atoms are in 45.6 g gold, Au
Gemiola [76]
<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

45.6 g Au ( 1 mol / 196.97 g ) (  </span>6.022 x 10^23 atoms / mole ) = 1.39x10^23 atoms Au

Complete the following table. Tell if the molecule is polar or nonpolar, draw the Lewis dot structure for the molecule, tell wha
andrew11 [14]

The complete table is shown in figure

a) NH3 is polar as the bonds between N and H are polar. Due to asymmetry in   the molecule the molecule is polar

The shape of molecule is trigonal pyramidal while its electronic geometry is tetrahedral.

b) CO2: it is a non polar molecule with polar bonds. The molecule becomes non polar as the dipole moment cancel each other. [Dipole moment is a vector quantity]

The shape is linear.
