The combination of nickel (III) cyanide and aluminum permanganate results in a redox reaction. Aluminum permanganate acts as an oxidizing agent, while nickel (III) cyanide acts as the reducing agent.

During the reaction, the aluminum permanganate oxidizes the nickel (III) cyanide to form nickel (II) cyanide and manganese dioxide:

2 Ni(CN)3 + 3 Al(MnO4)3 → 2 Ni(CN)2 + 3 MnO2 + 9 Al(OH)4

The oxidation of nickel (III) cyanide by aluminum permanganate occurs due to the transfer of electrons from the nickel (III) ion to the permanganate ion. This transfer is facilitated by the presence of water, which helps to solubilize the reactants and products.

Overall, the reaction between nickel (III) cyanide and aluminum permanganate results in the formation of nickel (II) cyanide and manganese dioxide, with aluminum hydroxide acting as a byproduct. The reaction is a prime example of a redox reaction, where one reactant is oxidized while the other is reduced.

Unfortunately, I cannot answer that question as there is not enough information available to determine the melting point of Ni(CN)3. The melting point of a compound depends on various factors such as its molecular structure, intermolecular forces, and purity. Additionally, experimental conditions such as pressure and heating rate can also affect the melting point. Therefore, without further information or experimental data, it is impossible to provide a precise answer to this question.

The molecular geometry of Ni(CN)3 is octahedral. The nickel ion (Ni) is located at the center, surrounded by six atoms including three cyanide ligands (CN-) that occupy the corners of an octahedron. The bond angle between the nickel ion and each of the cyanide ligands is approximately 180 degrees.

The electron domain geometry of Ni(CN)3 is octahedral. This is because of the presence of six electron domains around the central nickel atom, consisting of three CN- ligands and three lone pairs of electrons. The arrangement of these domains is symmetrical and maximizes distances between them, resulting in an octahedral molecular shape.

The hybridization of Ni in Ni(CN)3 is sp2. In this compound, the nickel atom is bonded to three cyanide ions (CN-), which act as ligands. Each ligand donates a lone pair of electrons to the Ni atom, forming three sigma bonds. This results in the formation of a trigonal planar geometry around the Ni atom. To accommodate this geometry, the Ni atom undergoes sp2 hybridization, where the 4s and two of the 4p orbitals hybridize to form three sp2 orbitals that are oriented in a trigonal planar arrangement. The remaining 4p orbital remains unhybridized and perpendicular to the plane of the sp2 orbitals.

In Ni(CN)3, the overall charge of the molecule is -3 since each CN ligand carries a -1 charge. Therefore, the sum of the oxidation states of all atoms in the molecule must be equal to -3.

Let x be the oxidation state of Ni in Ni(CN)3. The oxidation state of C in CN is -1, and there are three CN ligands, so the total oxidation state contributed by the CN ligands is -3. Setting up the equation for the sum of the oxidation states, we get:

x + (-3) = -3

Simplifying, we get:

x = 0

Therefore, the oxidation state of Ni in Ni(CN)3 is 0.

The CN ligand in Ni(CN)3 is a monodentate ligand, meaning that it can bond to the metal ion (Ni) through only one atom (the carbon atom in this case). Each Ni ion in the compound is coordinated with three CN ligands, forming a coordination number of 6 for Ni. The CN ligand is a strong-field ligand, which means that it forms a relatively stable bond with Ni and causes a large splitting of the d orbitals. This leads to a low-spin complex with a small magnetic moment. Overall, Ni(CN)3 is an example of a high-spin, octahedral coordination complex with monodentate CN ligands.

In Ni(CN)3, the coordination number of Ni is 6. This is because each CN ligand contributes one electron pair to form a coordination bond with Ni, and Ni has a total of 8 valence electrons available for coordination. Therefore, it can accommodate up to 6 CN ligands around it to satisfy the octet rule.

The molar mass of Ni(CN)3 can be calculated by adding up the atomic masses of each element in the compound, multiplied by their respective subscripts.

Ni: 1 x 58.69 g/mol = 58.69 g/mol

C: 3 x 12.01 g/mol = 36.03 g/mol

N: 3 x 14.01 g/mol = 42.03 g/mol

Therefore, the molar mass of Ni(CN)3 is:

58.69 g/mol + 36.03 g/mol + 42.03 g/mol = 136.75 g/mol

Note that it is important to use the correct atomic masses for each element, as they may vary depending on the isotope. In addition, when calculating molar mass, it is necessary to include all atoms in the formula, including any coefficients or subscripts.

Ni(CN)3 is a coordination compound and its boiling point cannot be determined solely based on its chemical formula. The boiling point of a compound depends on various factors such as intermolecular forces, molecular weight, and the presence of hydrogen bonding. However, it is worth noting that Ni(CN)3 is a highly toxic and reactive compound that can decompose at high temperatures, which may affect its boiling point. Further experimental analysis would be required to determine the exact boiling point of Ni(CN)3.
