Class 12th

Packing efficiency for both ccp and hcp structures are 74%

Z_ccp= Z_FCC = 4

Z_HCP = 6

$2Cr+3F{e}^{2+}\stackrel{n=6}{\to }2C{r}^{3+}+3Fe$

$?G^0=-n{E}^{0}F$

$170*{10}^3=-6*E^0*96500$

$E_{cell}^0=0.29V$

(Explanation can be elaborate)

For a region of constant electric potential

(1) The electric field may be uniform

(2) The electric field may be zero

(3) There can be no charge inside the region

IUPAC name : Propane-1, 2, 3-tricarboxylic acid.

Kjeldahl's method is not applicable to compounds containing nitrogen in nitro and azo groups and nitrogen present in the ring.

The name of this SI Unit Henry is derived from the name of the scientist who discovered the concept of inductance and electromagnetic induction, Joseph Henry. He was a scientist from America who supported the principles of Faraday and helped in bringing a revolution in the field of modern physics.

Energy of the complex $\frac{}{}{}_{}$ $=-\frac{2}{5}*4{?}_0+P$

For low spin $d^4$ ${}^{}$ cation

$=1.6{?}_0+P$

KIndly consider the following figure

${}_Z{}^{A}X+{}_1{}^{1}H\to {}_2{}^{4}He+{}_8{}^{16}O$

$Z+1=2+8?Z=9X\to F$

$A+1=4+16\Rightarrow A=19$

$\Rightarrow {}_Z{}^{A}X={}_9{}^{19}F$

${}_7{}^{14}N+{}_Z{}^{A}Y\to {}_1{}^{1}H+{}_6{}^{14}C$

$7+Z=1+6?Z=0$

$14+A=1+14?A=1$

$?{}_Z{}^{A}Y={}_0{}^{1}n$
