Explanation:

Formula of magnesium sulfite: [tex]\rm MgSO_3[/tex].

Look up the relative atomic mass of [tex]\rm Mg[/tex]. [tex]\rm S[/tex], and [tex]\rm O[/tex] on a modern periodic table:

The ionic compound [tex]\rm MgSO_3[/tex] consist of magnesium ions [tex]\rm {Mg}^{2+}[/tex] and sulfite ions [tex]\rm {SO_3}^{2-}[/tex].

Notice that [tex]\rm {Mg}^{2+}\![/tex] and [tex]\rm {SO_3}^{2-}\![/tex] combine at a one-to-one ratio to form the neural compound [tex]\rm MgSO_3[/tex]. Therefore, each [tex]\rm MgSO_3\![/tex] formula unit would include one [tex]\rm {Mg}^{2+}[/tex] ion and one [tex]\rm {SO_3}^{2-}[/tex] ion (that would be two ions in total).

Calculate the formula mass of one such formula unit:

[tex]\begin{aligned}&\; M(\mathrm{MgSO_3}) \\ = & \; 24.305 + 32.06 + 3 \times 15.999 \\ = & \; 104.362\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

In other words, the mass of one mole of [tex]\rm MgSO_3[/tex] formula units (which includes one mole of [tex]\rm {Mg}^{2+}[/tex] ions and one mole of [tex]\rm {SO_3}^{2-}[/tex] ions) would be [tex]104.362\; \rm g[/tex].

Calculate the number of moles of such formula units in that [tex]2.95\; \rm g[/tex] of [tex]\rm MgSO_3[/tex]:

[tex]\begin{aligned}n&= \frac{m}{M}\\ &=\frac{2.95\; \rm g}{104.362\; \rm g \cdot mol^{-1}} \approx 2.82670 \times 10^{-2}\; \rm mol\end{aligned}[/tex].

There are two moles of ions in each mole of [tex]\rm MgSO_3[/tex] formula units. Therefore, that [tex]2.82670 \times 10^{-2}\; \rm mol[/tex] of [tex]\rm MgSO_3\![/tex] formula units would include approximately [tex]2 \times 2.82670 \times 10^{-2}\; \rm mol \approx 5.65\times 10^{-2}\; \rm mol[/tex] of ions.

Answer:

Will group 2 elements lose electrons to bond with nonmetals in group 17 in a

1:2 ratio?

Explanation:

Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.

Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.

Answer:

Explanation:

Polar bonds also often contribute to a net dipole moment of a molecule. This basically means that there are partial charges that make a molecule overall polar. One example might be water: in H20, oxygen is very electronegative, and hydrogen is less so. This means that oxygen is more negative and hydrogen is more positive. This is why water is cohesive (can stick together): The positive ends stick to the negative ends.

To solve this we must be knowing each and every concept related to polar molecule.  Therefore, polar and nonpolar molecules are covalent compound.

A polar molecule is a type of chemical compound where there is an uneven distribution of electrons among the covalently bound atoms.

The term "polarity" refers to how unlike two molecules' electrical poles are from one another. If they are quite dissimilar, the species is said to be an extremely polar molecule.

Because of the more symmetrical distribution of the electrons, non-polar molecules do not have a lot of charges on their opposing sides. The fees are all offset by one another. Polar and nonpolar molecules are covalent compound.

Therefore, polar and nonpolar molecules are covalent compound.

Explanation:

From avogadro's number, we have that;

1 mole of atoms contain 6.022 × 10^(23) atoms

Therefore, 1.2 x 10^(48) atoms of copper will contain;

(1.2 x 10^(48) × 1)/(6.022 × 10^(23)) = 1.993 × 10^(24) moles
