Which of the following polyatomic ions will form an ionic compound with two sodium ions? CO32− HCO31− NO21− NO31−
BaLLatris [955]

Answer:

CO32−

Explanation:

We have to consider the valencies of the polyatomic ions involved. Recall that it is only a polyatomic ion with a valency of -2 that can form a compound which requires two sodium ions.

When we look closely at the options, we will realize that among all the options, only CO32− has a valency of -2, hence it must be the required answer. In order to be double sure, we put down the ionic reaction equation as follows;

2Na^+(aq) + CO3^2-(aq) ---------> Na2CO3(aq)

Magnesium has three stable isotopes. One has 12 neutrons the second has 13 and the third has 14. Which one is the most abundant?
fiasKO [112]

Answer:

12

Explanation:

If you look at the periodic table, you can see that magnesium has an atomic mass of 24.305.  Subtract the number of protons from this to get neutrons.

24.305 - 12 = 12.305

12.305 is the average amount of neutrons a magnesium atom can have.  A magnesium atom can have 12, 13, or 14 neutrons.  The average, based on the natural abundance, is 12.305.  To find which isotope is more abundant, you need to pick the number that is closest to the average.  This would make the most abundant isotope the one with 12 neutrons.
