The magnesium atom looses two electrons which are accepted by each of the fluorine atoms. (Option D).

<h3>What is an ionic bond?</h3>

An ionic bond is formed when two ions are formed by the loss or gain electrons. In this case, magnesium has to loose two electrons while fluorine will gain two electrons.

Thus, the correct steps in the formation of an ionic bond between these atoms are A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion (Option D).

weeeeeb [17]

Answer:

The answer is "\bold{CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)}"

Explanation:

When HCI is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:

CH_3COONa\ (aq) + HCl\ (aq)\longrightarrow CH_3COOH\ (aq) + NaCl\ (aq)\\\\

 In this, the CH_3COOH is a weak acid so, it not completely dissociated.

CH_3COONa \ (aq) \ \ and \ NaCl were strong electrolytes they are completely dissociated.

The HCl is a strong acid so, it is completely dissociated So, the net ionic equation is:

CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)

Number of miles of Xe in 12.00g of Xe
Korvikt [17]
1 mol of Xe has a mass of 131 grams
x mol of Xe has a mass of 12 grams.

1/x = 131/12 Set up proportion from the information above. Cross multiply
131x = 12 Divide by 13`
x = 12/131
x = 0.0916 mol <<<< ====

Just for fun
I don't know if a calculator would even tell me the number of miles in 12 grams of Xe

The diameter is 216 * 10^-12 meters. Maybe.
1 mol of anything is 6.02 * 10^23
0.0912 mols contain x atoms

1/0.0912 = 6.02 * 10^23 / x
x = 0.0912 *  6.02 * 10^23
x = 5.49 * 10 ^ 22 This thing is going to stretch out quite a ways.

1 atom = 312 * 10^- 12 meters.
5.049 * 10^22 = x meters.
x  = 312 * 10^-12 * 5.49 * 10^22
x = 1.7 * 10 ^10 km = 1.07 * 10 ^10 miles We're talking about beyond Pluto. 

I'm sorry I should delete this. If you want to you can. Take my answer for the number of mols. It's likely correct.
