Condensed electron configuration of :
Ga = [Ar] 3d¹⁰ 4s² 4p¹.
O = 1s² 2s² 2p⁴
Gallium belongs to group 13 of the periodic table with 3 valence electrons. Oxygen (Atomic number = 8 and electronic configuration = 2,6) belongs to group 16 of the periodic table with 6 valence electrons. To achieve the octet stability criteria 2 gallium atoms will donate their 3 electrons each to 3 oxygen atoms.
The 3 oxygen atoms due to their high electron attracting ability will accept those electrons resulting in Ga3+ cation and O₂⁻ anion.
Thus, the formula of their compound if Ga₂O₃.

Answer:
When fuels are burned in vehicle engines, high temperatures are reached. At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. When this nitrogen monoxide is released from vehicle exhaust systems, it combines with oxygen in the air to form nitrogen dioxide.

Answer:
Lewis acid is a substance that donates a lone-pair of electrons.
Explanation:
What is said in the statement corresponds to a Lewis base, not an acid. For example, NH3 is a Lewis base, since it is capable of donating its pair of electrons. Trimethylborane (Me3B) is a Lewis acid, since it is capable of accepting a solitary pair.
