In a face-centered cubic (FCC) structure, each atom is in contact with 12 other atoms, giving it a coordination number of 12.

In the complex [Co(NH3)6]3+, there are six ammonia (NH3) ligands coordinated to the cobalt ion, giving it a coordination number of 6.

A catalyst lowers the activation energy of a reaction, thereby increasing the reaction rate.

Adding a non-volatile solute increases the boiling point due to boiling point elevation.

Adding a non-volatile solute decreases the vapor pressure of the solvent due to the solute particles occupying space at the surface.

Heavy metals can be toxic to organisms, leading to bioaccumulation and harmful effects on ecosystems.

Increasing pressure shifts the equilibrium towards the side with fewer moles of gas. In this case, it shifts to the right, producing more NH3.

Increasing temperature generally increases the conductivity of an electrolyte solution due to increased ion mobility.

Increasing temperature increases the kinetic energy of particles, leading to potential phase change.

Increasing the concentration of reactants generally increases the rate of reaction due to more frequent collisions.

Increasing the size of the halogen decreases the bond strength, thus increasing the reactivity of haloalkanes in nucleophilic substitution.

For an endothermic reaction, increasing the temperature shifts the equilibrium to the right, thus increasing the value of Kc.

For most solid solutes, solubility in liquids increases with temperature due to increased kinetic energy of the molecules.

The density of a crystalline solid is calculated using the formula Density = mass/volume.
