Question 9
umka2103 [35]

Answer:

Answer: A. 3 mol  3 mol Al:

Explanation:

Te given balanced chemical equation is :

According to the stochiometry :

A: 3 mol  3 mol Al:

3 moles of chlorine reacts with 2 moles of aluminium

B. 2 mol  3 mol :

2 moles of aluminium  reacts with 3 moles of chlorine

C.  2 mol  2 mol Al

2 mol of aluminium produces 2 mol of  

D. 3 mol  2 mol  

3 moles of chlorine produces with 2 moles of  

Thus the conversion factor not used for mole to mole calculations is  3 mol  3 mol Al:

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 average atomic mass of the element?
morpeh [17]

The average atomic mass of element X is 14.007 u.

The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).

Thus,  

0.996 36 × 14.003 u =13.952 03 u

0.003 64 × 15.000 u = <u>0.054 60 u</u>

__________TOTAL = 14.007     u
