Answer:

Electronic configuration of Ga³⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰

Explanation:

Gallium is present in group 13.

It has 3 valance electrons.

Electronic configuration:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹

There are two possibilities of gallium to form cation.

By removing one 4p electron to form Ga +1 cation.

By removing two 4s electrons and one 4p to form Ga +3 cation.

Gallium is preset in group thirteen that's why common oxidation state is +3.

Electronic configuration of Ga⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁰

Electronic configuration of Ga³⁺:

Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰

If we have equal masses of copper at 80oC and water at 20oC and we put them together, what is the final temperature?

Ket [755]

Answer:

The final temperature will be close to 20°C

Explanation:

First of all, the resulting temperature of the mix can't be higher than the hot substance's (80°C) or lower than the cold one's (20°C). So options d) and e) are imposible.

Now, due to the high heat capacity of water (4,1813 J/mol*K) it can absorb a huge amount of heat without having a great increment in its temperature. On the other hand, copper have a small heat capacity (0,385 J/mol*K)in comparison.

In conclusion, the copper will release its heat decreasing importantly its temperature and the water will absorb that heat resulting in a small increment of temperature. So the final temperature will be close to 20°C

<u>This analysis can be done because we have equal masses of both substances. </u>
