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.

A student performs three trials of a titration of an acid with an unknown concentration. She compares her measured concentration
Viktor [21]

Answer:

There are many errors possible while titrating the acid of an unknown concentration with a base like NaOH.

Main error that leads to the error in results is misreading of the end point volume .

End point is when the reaction between the analyte and solution of known concentration has stopped .

Sometimes Burette is not straight enough to read the volume of the end point. One way to misread the volume of burette is by looking at the burette volume at an angle .

From above , volume seems to be higher. Indicators are used to indicate the color change of the reaction. In Acid-Base titrations , indicators first lighten up then changes its color.

So, error may have occurred in wrongly judging of the end point by color change of the indicator .

emmainna [20.7K]

Answer:

The symbol of each element is, Ne, Na, Mg, and Al.

Explanation:

Below is the list of elements that has an atomic mass of less than 19.3 u.

The atomic mass of Neon is 20.1797 u and the atomic number is 10.

The atomic mass of Sodium is 22.989769 u and the atomic number is 11.

The atomic mass of Magnesium is 24.305 u and the atomic number is 12.

The atomic mass of Aluminium is 26.981539 u and the atomic number is 13.

Here, the symbol of each element is, Ne, Na, Mg, and Al.
