K = 3.3 × 10^-4 s^-1

Time for 40% completion ; t

Using $K=\frac{2.303}{t}lo{g}_{10}\frac{{\left[R\right]}_0}{\left[R\right]}$  

3.3 × 10^-4 =   $\frac{2.303}{t}lo{g}_{10}\frac{{\left[R\right]}_0}{0.6{\left[R\right]}_0}$

  $t=\frac{2.303}{3.3}\times 10^4\times 0.22\Rightarrow t=25.58mins$            

so; the nearest integer is 26.

Yes. Many Indian students from middle-class or poor families go abroad using scholarships, education loans, and part-time jobs. Countries like Germany, Norway, France offer almost free tuition which helps students with less money.

Coordination no. of an atom in BCC is 8.

Yes, in some countries you can study under 20 Lakhs. With 20 Lacs INR, you can study in Germany, Italy, France, Poland and other European countries where tuition is free or low. But in USA, UK, Australia, 20 Lacs is only enough for one year. With scholarships, costs can reduce.

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

If you want top education plus jobs, then USA, UK, Canada, Australia, and Germany are the best for studying abroad. These countries have top universities, scholarships, and work options.

There is no single best country to study abroad. It depends on budget and goal. Germany, Canada, France are some of the cheapest and best study abroad destination.

The choice of going and studying abroad depends on your career plan. The best course to study abroad are Engineering, Computer Science, Business, Medicine, Data Science, and Artificial Intelligence.

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

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

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

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

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

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

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

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

$=3\times 6.02\times 10^{23}\times 3=9\times 6.02\times 10^{23}$  

$=5418\times 10^{21}$  

$\therefore x=5418$  

The best bank for education loans in India for studying abroad is often the State Bank of India (SBI). It's a public sector bank which offers student loans with attractive ROI. Other than this, Punjab National Bank, Bank of Baroda, HDFC Bank, and ICICI Bank are some reputed banks which offer education loans.

Under its Global Ed Vantage scheme, you can avail up to INR 1.5 crore. Also, with flexible repayment up to 15 years. Comparing terms and rates based on your specific needs is advised.

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

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.

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

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

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

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

= 0.2 = 2 × 10^-1

So; x = 2

The Earth's magnetic field makes a magnetic inclination (dip) or angle between Earth's overall magnetic field and the horizontal plane at a particular location. It shows how much the magnetic field is tilted from the horizontal.

tan I = B_V / B_H,

where, B_V is the vertical component and B_H is the horizontal component of the Earth's magnetic field.

(A) SiO? has three-dimensional network structure of Si – O bonds; while carbon dioxide consists of discrete CO? molecules. SiO? is solid, whereas CO? is a gas
(B) Because of its great affinity for oxygen, Si always occurs as the oxide, silica (SiO? ) or in the form of silicates, which are the compounds of SiO? with other metal oxides.
(C) SiO? + 2Mg → Si + 2MgO
(D) The reluctance of silicon to form pπ – pπ bonds to itself is clearly shown by the fact that silicon does not exist in graphite-like structure, but only in diamond like structure.

W = 4.5 g

M.W = 90

V = 250 ml

Using M = $\frac{W}{M.W\times V}\times 1000$  

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

M = 2 × 10^-1 M

So, x = 2

The balanced equation is :

$S_8\left(s\right)+12O{H}^{-}\left(aq\right)\to 4S^{2-}\left(aq\right)+2S_2{O}_3^{2-}\left(aq\right)+6H_{2}O\left(\mathcal{l}\right)$           

Here ; a = 12
