4. Iron oxides are mixed with limestone and coke in order to decompose carbonates and oxidize sulfides. This mixture is then fed into the blast furnace. Many reactions take place in different temperature ranges of the blast furnace. By oxidizing impurities from cast iron in a reverberatory furnace which is lined by hematite, wrought iron or malleable iron is obtained. This is the purest form of commercial iron. This can be shown with the following reaction:

Fe2O₃ + 3C → 2Fe + 3CO.

Sulfur, silicone and phosphorus are oxidized and passed into the slag and removed as impurities when limestone is added as a flux to it.

The admission process for B Tech Computer Science and Engineering (BTech CSE) typically involves the following steps: Entrance Exams: Most of the best BTech in CSE colleges require candidates to appear for national entrance exams like JEE Main, JEE Advanced, MHT CET, TS EAMCET, Andhra Pradesh EAMCET, COMEDK UGET, etc.

criteria include the completion of Class 12 in the Science stream and securing 50 to 75 percent marks in Physics, Chemistry, and Mathematics subjects

The key highlights of Amity Global Business School Pune placements in recent past are presented below:

As per the Pearl Academy Mumbai admission criteria, it does not offer direct admission for its BBA programmes. Pearl Academy Mumbai BBA admission is based on an accepted entrance exam, namely the Pearl Academy Entrance Exam. The selection process includes the General Proficiency Test (GPT), Design Aptitude Test (DAT), and a personal interview. However, it is essential for candidates to fulfil the requisite eligibility criteria before applying for the programme.

Yes, there are internships available after completing a Diploma in F&B courses. In fact, many Diploma courses in this filed include an internship as a mandatory or highly recommended part of the curriculum to practical experineces. 

3. From Ellingham diagram, we know that ΔG^° _{(C, CO)}  < ΔG^° _{(Fe, Fe)}, the following reactions are:

C+ $\frac{1}{2}$ O₂→CO

2Fe+O₂→2FeO

Therefore, FeO can be reduced to Fe by coke. 

25. Option (i) Very low value of electrical conductivity in the molten state is correct since in molten state, the ionic solids possess free ions which help in the conduction of electricity. Due to the availability of these free ions the electrical conductivity of ionic compounds in molten state is found to be very high. 

24. Option (iii) (C) and (D) is correct since Iodine is a non-polar molecular solid which acts as an insulator while H₂O is a hydrogen bonded molecular solid which also acts as an insulator. Whereas Mg is a metal and acts as a conductor in solid and in its molten state and TiO is also an ionic solid which acts as an insulator in solid state but acts as a conductor in molten and in aqueous solutions.

2. Extraction of chlorine from brine is an oxidation method. The reactions involved are:

2Cl⁻ + 2H₂O → 2OH⁻ + H₂ + Cl₂

For this reaction, the value of ΔG°=+422 kJ, which is positive. Using the formula ΔG°=−nE°F, we get a negative value of E° =−2.2 V.

Since,  E°=−2.2 V, it would naturally require an external voltage greater than 2.2 V for the reaction to occur.

The given differential equation is:

$\begin{array}{l}{e}^{x}dy+(y{e}^x+2x)dx=0\\ \Rightarrow e^x\frac{dy}{dx}+y{e}^x+2x=0\\ \Rightarrow \frac{dy}{dx}+y=-2x{e}^{-x}\end{array}$

This is a linear differential equation of the form

$\begin{array}{l}\frac{dy}{dx}+Py=Q,whereP=1\&Q=-2x{e}^{-x}\\ Now,I.F.=e^{{\displaystyle \int Pdx}}=e^{{\displaystyle \int dx}}=e^x\end{array}$

The general solution of the given differential equation is given by,

$\begin{array}{l}y(I.F.)={\displaystyle \int \left(Q\times I.F.\right)dx+C}\\ \Rightarrow y{e}^x={\displaystyle \int (-2x{e}^{-x}.e^x)dx+C}\\ \Rightarrow y{e}^x=-{\displaystyle \int 2xdx+C}\\ \Rightarrow y{e}^x=-x^2+C\\ \Rightarrow y{e}^x+x^2=C\end{array}$

Therefore, option (c) is correct.

Some core industries that hire BA Public Administration graduates in India and abroad are mentioned in the list below

Economic Development Agencies
Government Sectors
Indian Civil Services
Research & Academia
Corporate
Public and Social Services
Police Firms
NGOs

The integrating factor of the given differential equation  $\frac{dx}{dy}+P_{1}x=Q_1$

The general solution of the differential equation is given by,

$\begin{array}{l}x(I.F.)={\displaystyle \int \left(Q\times I.F.\right)dy+C}\\ \Rightarrow x.e^{{\displaystyle \int P_{1}dy}}={\displaystyle \int \left(Q_1{e}^{{\displaystyle \int P_{1}dy}}\right)}dy+C\end{array}$

Hence, the correct answer is C.

GADVASU Ludhiana has a rich legacy of knowledgeable and experienced faculty members. The majority of the faculty staff is PhD-holding and possesses vast field experience in their respective disciplines. Dr. Jatinder Paul Singh Gill presides over the post of Vice-Chancellor and convenes the major administrative decisions at the university. Other faculty staff at Guru Angad Dev Veterinary and Animal Sciences University include Dr. Suresh Kumar Sharma as the Registrar.

The total tuition fee for the BBA programme at Pearl Academy Mumbai is INR 18.3 lakh. Apart from the tuition fee, the fee structure may comprise various fee elements, such as the admission fee, hostel charges, security deposit, and other miscellaneous charges. The fee can be paid semi-annually once the admission is confirmed. However, it must be noted that the mentioned fee is taken from the official website/sanctioning body. It is still subject to change and, hence, is indicative.

The given differential equation is:

$\begin{array}{l}\frac{ydx-xdy}{y}=0\\ \Rightarrow \frac{ydx-xdy}{xy}=0\\ \Rightarrow \frac{1}{x}dx-\frac{1}{y}dy=0\end{array}$

Integration both sides, we get:

$\begin{array}{l}log\left|x\right|-log\left|y\right|=logk\\ \Rightarrow log\left|\frac{x}{y}\right|=logk\\ \Rightarrow \frac{x}{y}=k\\ \Rightarrow y=\frac{1}{k}x\\ \Rightarrow y=Cx,where,C=\frac{1}{k}\end{array}$

Therefore, option (C) is correct.

Guru Angad Dev Veterinary and Animal Sciences University is located in the quaint and green surroundings of Ludhiana city in Punjab. As such, the university campus is well-connected and accessible via different modes of transportation.

For candidates arriving via the Ludhiana Airport, a 30-minute drive would get them to the GADVASU campus. The students arriving at Ludhiana Junction Railway Station can take a mere 15-minute drive to reach the campus of Guru Angad Dev Veterinary and Animal Sciences University.
