A catalyst  is a substance that speeds up the rate of a chemical reaction  but is not consumed during the course of the reaction.
A catalyst will appear in the steps of a reaction mechanism,but it will not appear in the overall chemechal reaction
i hoped this helped 
by the way can you mark me the brainliest
.since i was the only one to answer youre question
;P thanks bye

Ligand field diagram for octahedral complex explain briefly
stich3 [128]

The ligand field diagram for octahedral complex is explained here.

In a free metal ion, all the five d-orbitals are degenerate (i.e, having equal energies). But according to crystal field theory, under the influence of ligand field, degenracy of d-orbital is destroyed and they split into two or more energy levels. The difference in energy between two sets of d-orbitals is called Crystal Field Splitting Energy (CFSE). The extent of splitting depends upon the strength of ligand. A strong ligand causes greater splitting whereas weak ligand causes smaller splitting.

In octahedral complex, under the influence of ligand field, degenerate five d-orbitals  split into two sets of orbitals -one is t_{2g} and another one is e_{g}. t_{2g} orbital consists of d_{xy} , d_{xz} , d_{yz} and e_{g} orbital consists of d_{x^{2}-y^{2}  }  and   d_{z^{2} } orbitals.

The crystal field splitting diagram for octahedral complex is attached here.

In the diagram, Δo is crystal field splitting energy (CFSE).

What is the molarity of a solution that is 26.0% by mass in phosphoric acid, H3PO4, and that has a density of 1.155 g/mL?
steposvetlana [31]

Answer: The molarity of a solution that is 26.0% by mass in phosphoric acid is 3.06 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

n = moles of solute

V_s =volume of solution in ml

Given : 26.0 g of phosphoric acid in 100 g of solution.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{26.0g}{98g/mol}=0.265moles

Volume of solution =\frac{\text {Mass of solution}}{\text {Density of solution}}=\frac{100g}{1.155g/ml}=86.6ml

Molarity=\frac{0.265\times 1000}{86.6ml}=3.06M

Molarity of a solution that is 26.0% by mass in phosphoric acid is 3.06 M
