Answer from: deepunalli300p3ur3i

The order of ionization energies from the highest to smallest is as below

Chlorine -1 ( highest)

phosphorus -2

magnesium-3

sodium-4 (smallest)

Explanation

sodium, magnesium,phosphorus and chlorine are in period three in periodic table.
The trend of ionization energy across period 3 is that it increases across the period ( from the left to the right).
The ionization energy increases across the period 3 because there are more protons in each nucleus which led to increase in nuclear charge across the period. ( from left to the right)
This led to increase in force of attraction between nucleus and outer electron.( from the left to the right)
among the four element given above from the left of period 3 , Sodium is 1st element followed by magnesium, then phosphorus and then chlorine.
Therefore since sodium is in left side it has the smallest ionization energy while chlorine has the highest ionization energy since is is located at the fur right of period 3.

Answer from: Quest

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

Answer from: Quest

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
