Hello there!
3. In this case, according to the given question, it turns out possible for us to say that any chemical formula, for an ionic compound, has the cation (positive) on the left and the anion (negative) on the right; thus, since Mg is a metal, which tends to lose electrons and become positively charged whereas the Cl is a nonmetal, which tends to gain electrons and become negatively charged, we have the following:
![Mg^{2+}Cl^-\\\\Mg^{2+}Cl^-_2\\\\MgCl_2](https://tex.z-dn.net/?f=Mg%5E%7B2%2B%7DCl%5E-%5C%5C%5C%5CMg%5E%7B2%2B%7DCl%5E-_2%5C%5C%5C%5CMgCl_2)
4. In this case, since lithium is a metal, as well as magnesium, it is not possible for them to switch around their charges as they will not be bonded because they will be repelled rather than attracted because of their equal positive charges.

Answer:
I believe it is d but the letter on the chart is e so your answer option is option d.
Explanation:
When we speak of hydrogen, the assumption is that it is hydrogen gas, H2, and not atomic hydrogen. Since hydrogen is diatomic, 1 mol of H2 has a mass of 2.0 grams. Therefore, 2 moles will have a mass of 4.0 grams.
Likewise, 0.5 grams is 1/4 of the mass of 1 mole (2.0 g), so the answer is 0.25 mol H2.
You can even set up a conversion factor to get the answer.
0.5 g H2 x (1 mol H2 / 2.0 g H2) = 0.25 mol H2
