The correct answer is In2O3 < Ga2O3 < Al2O3.
Ga2O3, Al2O3, and In2O3 are the oxides to rank in order of increasing aqueous acidity.
According to the contemporary periodic table's rule, an oxide group's acidity decreases.
The oxidation state of Gallium (Ga) in Ga2O3 = +3
The oxidation state of Aluminium (Al) in Al2O3 = +3
The oxidation state of Indium (In) in In2O3 = +3
From modern periodic table, the order of elements in group 3A is as below:
Baron (B), Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl)
Thus, we can get the oxides in order of increasing their aqueous acidity as below:
In2O3 < Ga2O3 < Al2O3

id say its C mechanical energy making the wheels turn.
Test tube of ammonium chloride (NH4Cl) being heated over a bunsen burner flame. Ammonium chloride decomposes readily when heated, but condenses in the cooler area at the top of the test tube. This is a reversible reaction, where the ammonium chloride decomposes into the gases ammonia (NH3) and hydrogen chloride (HCl).
Answer:
<h2>9.93 × 10²³ atoms</h2>
Explanation:
The number of atoms of potassium can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.65 × 6.02 × 10²³
We have the final answer as
<h3>9.93 × 10²³ atoms</h3>
Hope this helps you
