The electron affinity of an element is positive if energy is absorbed during the process of accepting an electron and negative i
julsineya [31]

Answer:

See explanation

Explanation:

Electron affinity is the energy released when an extra electron is added to a neutral gaseous atom. A negative value of electron affinity indicates that energy is given out and vice versa.

Metals have positive electron affinity since electrons rarely accept electrons, so;

Na(g)+ 1e^- → Na^-(g)      positive

Mg(g)+1e^- → Mg^-(g)      positive

For the last case; Br(g)+ 1e^- → Br^-(g), the electron affinity for the non-metals is negative. hence the answer

When looking into a tall glass of ice tea, you observe the tea looks darker when looking down from top to bottom, than when look
liubo4ka [24]

Answer:

Difference of path length

Explanation:

When we look into glass of ice tea, from top to bottom path length will be more as compared to when we look from side of the glass.

According to Beer Lambert law, absorbance is proportional to the path length. Path length is the distance that light travels through the material.

More path length will lead to more absorbance of light and more the absorbance more the darker tea looks.

Moreover, tea is a homogeneous solution, therefore, concentration of will be same through out the solution. Since, concentration is same, therefore, the effect of gravity will be also be same on all particles.

Therefore, difference in path length is responsible .

So, the correct option is option a, difference in path length
