Answer:
HgSO₄
Explanation:
% => g => moles => ratio => reduce => empirical ratio
%Hg = 67.6% => 67.6g/201g/mol = 0.34mol
%S = 10.8% => 10.8g/32g/mol = 0.34mol
%O = 21.6% => 21.6g/16g/mol = 1.35mol
Hg:S:O => 0.34:0.34:1.35
Reduce to whole number ratio by dividing by the smaller mole value...
Hg:S:O => 0.34/.34:0.34/.34:1.35/.34 => Empirical Ratio = 1:1:4
∴ Empirical Formula is HgSO₄
Answer:
D. none of the above
Explanation:
A. is wrong because pressure and volume have an inverse relationship. When one increases the other decreases, this is not an option.
B. is wrong because temperature and volume have a proportional relationship. One one goes up, the other goes up or vice versa.
C. is wrong because volume cannot increase the then decrease at the same time.
The complex ion has a charge of -3 which means it is an anionic complex. The nomenclature for this complex can be broken in to two parts. The part that contains the cyano and the part that contains aluminium.
Cyano Ligand
There are 6 cyanide ions in the complex ion and so we assign the prefix hexa to explain the presence of 6 anions. This makes our ligand part be name hexacyano.
The aluminium part
Since the metal ion ends up in an anionic complex we add -ate at the end of aluminium to show that we have an anionic complex.
Henceforth we combine the two parts and start with the ligand in naming the complex. is called hexacyanoaluminate
