An excited state electron configuration of Gallium (Ga) might be [Ar] 4s2 3d9 4p2, as this configuration represents an electron having absorbed energy and moved from the 3d to the 4p level.
The electron configuration of an atom in its ground state is the arrangement of electrons in the lowest possible energy levels (the 'normal' arrangement). For the element Gallium (Ga), the ground state electron configuration is [Ar] 4s2 3d10 4p1. However, when an atom is in an excited state, one or more electrons have absorbed energy and moved to a higher energy level. An electron configuration for an excited state of Gallium might look like [Ar] 4s2 3d9 4p2 as an electron from the 3d level has absorbed energy and moved to the higher 4p level.

ahhh....Double displacement reaction or precipitation reaction.(both are correct im not guessing)
Answer:
92.1
Explanation:
1.57 * 58.69
H2SO4
KOH
H2O
Answer:
The answer is C.
Explanation:
Because, KOH is the highest PH in the molecule(s).
B. A sample of 2.00 g of O2 is removed.
C. A sample of 4.00 g of O2 is added to the 4.80 g of O2 gas in the container.
By using the ideal gas law and molar mass calculations, the final volumes are found to be A. 65.0 L, B. 8.75 L, and C. 27.5 L.
To calculate the final volume when additional O2 is added or when some O2 is removed, we can use the concept of the molar mass and the ideal gas law that states that volume is directly proportional to the amount of gas, assuming pressure and temperature is constant.
The molar mass of O2 is approximately 32.00 g/mol.
A. 0.500 moles of O2 is added. This equals 0.500 * 32 g = 16 g. The total mass in the system is now 20.8 g. If the original 15.0 L represented 4.80 g, now 20.8 g would represent 15.0 L * 20.8/4.80 = 65.0 L.
B. 2.00 g of O2 is removed. So, the total mass in the system is now 2.80 g. If the original 15.0 L represented 4.80 g, now 2.80 g would represent 15.0 L * 2.80/4.80 = 8.75 L.
C. 4.00 g of O2 is added. So, the total mass in the system is now 8.80 g. If the original 15.0 L represented 4.80 g, now 8.80 g would represent 15.0 L * 8.80/4.80 = 27.5 L.
