The balanced equation is
2Al + 2KOH + 6H2O -----> 2K[Al(OH)4 + 3H2.
From the above we see that 2 moles of K react with 2 moles of Al.
So 2 .94 moles of aluminium will react with 2.94 moles of potassium (answer)
In the sequence of nitrogenous bases
I couldnt see any choices but if any of the awnsers mention the skateborder having pontential energy turning into kinetic energy that one would be right
The given complex ion is as follow,
[Ru (CN) (CO)₄]⁻
Where;
[ ] = Coordination Sphere
Ru = Central Metal Atom = <span>Ruthenium
CN = Cyanide Ligand
CO = Carbonyl Ligand
The charge on Ru is calculated as follow,
Ru + (CN) + (CO)</span>₄ = -1
Where;
-1 = overall charge on sphere
0 = Charge on neutral CO
-1 = Charge on CN
So, Putting values,
Ru + (-1) + (0)₄ = -1
Ru - 1 + 0 = -1
Ru - 1 = -1
Ru = -1 + 1
Ru = 0
Result:
<span>Oxidation state of the metal species in each complex [Ru(CN)(CO)</span>₄]⁻ is zero.
