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
Answer:
The calculation of a standard deviation involves taking the positive square root of a nonnegative number. As a result, both standard deviations in the formula for the slope must be nonnegative. ... Therefore the sign of the correlation coefficient will be the same as the sign of the slope of the regression line.
Explanation:
I think the answer is A.
A. the speed of the walkway multiplied by the speed at which she is walking
The speed she is walking accelerates her speed by the base speed of the walkway.
