(a)
Interpretation:
The ionic compounds to be matched with its corresponding diagrams.
Concept Introduction:
In the formula of the compound, the sum of the charge of cation and anion must be equal to zero. The ration of cation and anion to be known in order to arrive the formula of a compound.
Rules for Nomenclature of ionic compounds:
- The name of the cation is followed by the name of the anion.
Covalent bonding: A covalent bond is formed by sharing of electrons (equally or partially polarized) between the two non-metals.
Octet rule: By obtaining eight electrons around the valence shell of an element, then compound satisfied the octet rule and thus, achieved the electron configuration of noble gas.
Diagrammatic representation of ionic compound used: The ions in the ionic compound are represented in spheres; where the green sphere represents the cation and the red sphere represent the anions.

- Using reaction free energy to predict equilibrium composition Consider the following equilibrium: N2 (g) + 3H2 (g) = 2NH3 (g) AG⁰ = -34. KJ Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of N2 tend to rise or fall? ☐ x10 fall Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fall by adding H₂? Similarly, if you said the pressure of N2 will tend to fall, can that be changed to a tendency to rise by adding H₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H₂ needed to reverse it. Round your answer to 2 significant digits. yes no ☐ atm ☑ 5 00. 18 Ararrow_forwardi need help with the followingarrow_forwardUsing reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NO(g) +Cl₂ (g) = 2NOC1 (g) AGº = -41. kJ Now suppose a reaction vessel is filled with 8.90 atm of chlorine (C12) and 5.71 atm of nitrosyl chloride (NOC1) at 1075. °C.

- Identifying the major species in weak acid or weak base equilibria The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row.
