I think that marijuana should be legalized for recreational use. It's not really bad for you and it doesn't cause problems like violence. If marijuana was the most abused substance rather than alcohol it would be an improvement.
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

The answer is 3 moles as per given balanced equation one mole Zn produces 1mole Hydrogen
when reacted with excess acid.
<span>So 3 moles Zn will give 3moles Hydroge</span>
Answer:
(a) X electrode
(b) Y electrode
(c) Y electrode
(d) X electrode
(e) Y electrode
Explanation:
<em>A galvanic (voltaic) cell has the generic metals X and Y as electrodes. X is more reactive than Y, that is, X more readily reacts to form a cation than Y does.</em>
In the X electrode occurs the oxidation whereas in the Y electrode occurs the reduction.
Oxidation: X(s) → X⁺ⁿ(aq) + n e⁻
Reduction: Y⁺ˣ(aq) + x e⁻ → Y(s)
<em>Classify the descriptions by whether they apply to the X or Y electrode.
</em>
<em>(a) anode.</em> Is where the oxidation takes place (X electrode).
<em>(b) cathode.</em> Is where the reduction takes place (Y electrode).
<em>(c) electrons in the wire flow toward.</em> Electrons in the wire flow toward the cathode (Y electrode).
<em>(d) electrons in the wire flow away.</em> Electrons in the wire flow away from the anode (X electrode).
<em>(e) cations from salt bridge flow toward.</em> Cations from the salt bridge flow toward the cathode (Y electrode) to maintain the electroneutrality.
Answer: An example is <u>sodium ethoxide (NaOCH2CH3) dissolved in ethanol (CH3CH2OH).</u>
Hope this helps!
