Chemistry

Coordination no. of an atom in BCC is 8.

To stop bleeding, FeCl? is applied locally because FeCl? causes denaturation of proteins present in blood. It is a case of coagulation.

$E_{1_H}=-2.2*10^{-18}J$

$Li\to L{i}^{+2}+2e^{-},n=2$

$E_{L{i}^{+2}}=E_{1H}*\frac{Z^2}{n^2}=-2.2*10^{-18}*\frac{3^2}{2^2}$

$\lambda =4*10^{-8}$ m

$d=\frac{ZM}{N_A{a}^3}=\frac{4*58.5}{6.02*10^{23}*a^3}$

$43.1=\frac{4*58.5}{6.02*10^{23}*a^3}$

$\therefore a=2.08*10^{-8}cm$

$\therefore r_{N{a}^{+}}+r_{C{l}^{-}}=1.04*10^{-10}$ m

Molar mass of C₇H₅N₃O₆ = 12 * 7 + 1 * 5 + 14 * 3 + 16 * 6 = 84 + 42 + 96 = 227 g/mol

Number of moles =  $\frac{681}{227}$  = 3 mol

$\therefore$  number of N-atoms

$=3*6.02*10^{23}*3=9*6.02*10^{23}$  

$=5418*10^{21}$  

$\therefore x=5418$  

Alitame is an artificial sweetener. It is a second generation of dipeptide sweetener. It is 200 times sweeter than sucrose.

Using $\lambda =\frac{h}{\sqrt[]{2qVm}}$  

${\lambda }_{Li}=\frac{h}{\sqrt[]{2*3e*V*8.3m}}$  m = mass of proton

${\lambda }_p=\frac{h}{\sqrt[]{2*e*V*m}}$  

$\frac{{\lambda }_{Li}}{{\lambda }_p}=\sqrt[]{\frac{2eVm}{2*24.9eVm}}$            

= 0.2 = 2 * 10^-1

So; x = 2

λ = h/p there is inverse relation between de-Broglie wavelength and momentum, hence the graph will be rectangular hyperbola.

Micelles are not formed because it formed above CMC.

W = 4.5 g

M.W = 90

V = 250 ml

Using M = $\frac{W}{M.W*V}*1000$  

$M=\frac{4.5}{90*250}*1000=0.2$       

M = 2 * 10^-1 M

So, x = 2
