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
Because it heats up the earth just like a blanket.
The solubility of gas in water is inversely proportional to the temperature. That means cool waters can hold more gases than hot waters. So when the oceans continue to warm all the green--houses gases present in oceanic waters will be released into to the atmosphere. This would further lead to the heating up of the planet. The global climate would keep changing and the temperature of the planet would increase further. Therefore, when the oceans continue to warm the amount of green-house gases cannot be sequestered by the oceans (as the temperatures are high) and so this would further enhance the greenhouse effect.
Tap water contains many dissolved ions that are required to carry an electric current, whilst distilled water contains no or relatively low amounts of dissolved ions. the absence of ions in the distilled water accounts for the low to zero conductivity of the water
hope that helps!
