Answer:
Square planar
Explanation:
Ni^2+ is a d8 ion. It could exist in either a square planar or a tetrahedral geometry depending on the identity of the ligand. However, strong field ligands often lead to a square planar geometry owing to a greater crystal field splitting.
From the splitting diagrams of nickel II ion in tetrahedral and square planar geometries, it can easily be seen that a diamagnetic complex only arises from the square planar geometry.
Note that both tetrahedral and square planar geometries involve a coordination number of four.
Answer:
14 is this value for a molecule of 
.
Explanation:
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
Number of total outer valence electrons is carbon = 4
Number of total outer valence electrons is hydrogen = 1
Number of total outer valence electrons is chlorine = 7
For total number of outer electrons is
14 is this value for a molecule of .
Answer:
Vapour pressure of liquid is affected by its TEMPERATURE, TYPE OF LIQUID, ADDITION OF SOLUTES.
Explanation:
Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid. Mathematically, the vapor pressure of liquid is written as:
In (Pvap) = -ΔHvap / R * (1/T) + C
ΔHvap is the enthalpy of vaporization and it is constant for specific liquid, T is the temperature and C is a constant. Temperature therefore affect the vapor pressure of a liquid as increase in temperature can cause an increase in vapor pressure.
The type of liquid also affect the vapor pressure. If the molecules bind to each other strongly in the liquid, it increases vapor pressure to be exerted by the liquid but if the type of liquid is one with weak forces of attraction, the vapor pressure is reduced.
Addition of solute to the liquid increases the boiling temperature of liquids thereby reducing it's vapor pressure.
Explanation:
Matter can be categorized into substances and mixtures.
Matter is anything that has mass and occupies spaces.
Substances are distinct matter with the following properties:
- All parts are the same throughout i.e homogeneous
- Their composition is definite
- They cannot be easily separated or broken down into simpler substances by physical means
- Separation by physical means is not easy
- They have a unique set of physical properties.
Mixtures have the following properties:
- Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
- Their constituents retains their identity
- They can easily be separated by physical means
- They have a broad range of physical properties.
