(a)
Interpretation:
The systematic name and the chemical formula for ferric bromide have to be written.
Concept Introduction:
In the older nomenclature system, an “–ous” ending is used to indicate the lower common ionic charge, and an –ic ending is used to indicate the higher common ionic charge.
Some of the examples are shown below,
Figure 1
Chemical formula:
- 1) The chemical formula of binary compound from a pair of its constituent ion has to be written.
- 2) The coefficients of the ions with the magnitude of the charge on each of the ions have to be crossed multiplied. This is done to neutralize charge on the binary compound.
- 3) The oxidation state of the metal is written in roman numbers in the brackets
(b)
Interpretation:
The systematic name and the chemical formula for stannic nitride have to be written.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The systematic name and the chemical formula for ferrous bromide have to be written.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The systematic name and the chemical formula for aurous sulphide have to be written.
Concept Introduction:
Refer to part (a).

- 7. Magnesium is found in nature in the form of carbonates and sulfates. One of the major natural sources of zinc is zinc blende (ZnS). Use relevant concepts of acid-base theory to explain this combination of cations and anions in these minerals. (2 points)arrow_forward6. AlF3 is insoluble in liquid HF but dissolves if NaF is present. When BF3 is added to the solution, AlF3 precipitates. Write out chemical processes and explain them using the principles of Lewis acid-base theory. (6 points)arrow_forward5. Zinc oxide is amphoteric. Write out chemical reactions for dissolution of ZnO in HCl(aq) and in NaOH(aq). (3 points)arrow_forward

In this technique, a gaseous beam of anions of an element is bombarded with photons from a laser. The photons knock electrons off some of the anions, and the energies of the emitted electrons are detected. The incident radiation had a wavelength of 1064 nm, and the emitted electrons had an energy of 0.137 eV. Although the analysis is more complicated, we can obtain an estimate of the electron affinity from the energy difference between the photons and the emitted electrons. What is the electron affinity of thulium in electron volts and in kilojoules per mole?arrow_forwardBe sure to answer all parts. The following alkyne is treated with 03 followed by H₂O.
