(a)
Interpretation: The given property of the ionic compound related to the electrical conductivity needs to be discussed.
Concept Introduction:
A chemical compound can be formed by either ionic bond or covalent bond between bonded atoms. The ionic compound is formed by opposite charge ions; cations and anions. The covalent compound is formed by sharing of electrons between bonded atoms.
Atoms always take the way which is easier or involves less number of electrons. Therefore the atom with 1, 2, 3 valence electrons usually tend to loss electrons and form cation whereas the atom with 4, 5, valence electrons usually share electrons to form covalent bond. The atoms with 6, 7 valence electrons tend to form anion by gain of electron.
(b)
Interpretation: The reason of high melting and boiling point of ionic compound needs to be explained.

- 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.
