Concept explainers
(a)
Interpretation:
The coordination number of unknown metal has to be identified.
Concept Introduction:
Coordination number:
The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.
(b)
Interpretation:
The group bonded to unknown metal is ionically and covalently has to be explained.
Concept introduction:
The formation of an ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal. Covalent Bonding: Bonding between non-metals consists of two electrons shared between two atoms.
(c)
Interpretation:
The stereochemistry of red and blue forms has to be explained.
Concept introduction:
Geometry of coordination compounds: The study of geometry of the coordination compound helps in understanding the physical and chemical property of the compound.
Stereoisomer: The same molecular formula but different with the arrangements of atoms around the metal ion. The Ligands are arranged differently in coordination compounds.
Geometric isomers: stereoisomers that cannot be interconverted without breaking the

- The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes.
