a) Pb3O4
b) KO2
c) Na2O2
d) Li2O2
Answer: (B), KO2 Superoxides liberate oxygen with water.
- Aluminium reacts with sulfuric acid to form aluminium sulfate and hydrogen. What is the volume of hydrogen gas in litres (L) produced at 300 K and 1.0 atm pressure, when 5.4 g of aluminium and 50.0 mL of 5.0 M sulfuric acid are combined for the reaction?
(Use the molar mass of aluminum as 27.0 g mol−1, ???? = 0.082 atm L mol−1 K−1)
Answer: 2Al + 3H2SO4 → Al2(SO4)3 + 3H2
Mole of Al taken = 5.4 / 27 = 0.2
Mole of H2SO4 taken = 50 X 5 / 1000 = 0.25
As 0.2 / 2 > 0.25 / 3, H2SO4 is limiting reagent
Now, moles of H2 formed = 3 / 3 X 0.25 = 0.25
Therefore Volume = 0.25 x 0.082 x 300 / 1 = 24.6 / 4 = 6.15 L

Ans. Many aspirants go through the same conflict. The preference depends on your career priorities and aim. Some points are discussed below which may be helpful in deciding. If you are solely focused on JEE Advanced and have a decent score in JEE Main, then it is better to take the date after JEE Advanced. A good score in JEE Main will give you a backup and you can completely focus on JEE Advanced this way. If you didn’t do well in JEE Main and have lesser hope to score good marks, then you can take BITSAT before JEE Advanced. It is because delaying will increase the pressure. If your priority is BITSAT then it is better to be fully focused on this exam and go for the 3rd or 4th day of the exam. It will give you sufficient time to review the previous paper. If you are not sure about your preference then it will be better to attempt the exam prior to JEE Advance. For most exam aspirants, JEE Advanced is the dream from the beginning and it will be better to end the journey with your initial aim. Thus, you should choose the date as per your priority and comfort. Decide by judging your nervousness, preparation and then give priority to your choice. Read more

Ans. To join a reputed college, Indian students are required to give JEE-Main and JEE-Advanced. Cracking these exams with a top rank gives you the opportunity to join top National Institutes of Technology (NITs) and Indian Institutes of Technology (IITs). Admission into such reputed colleges, kickstart your Engineering career. Although both JEE-Main and JEE-Advanced are Engineering entrance exams, both have severe dissimilarities. The aspects of these dissimilarities have been discussed below. Level of difficulty: JEE-Advanced is far more difficult than JEE-Main. The primary focus of JEE-Main is to evaluate the candidates' knowledge of their class 11th and 12th syllabus while JEE-Advanced is taken to evaluate the analytical and problem-solving skills of the students. Syllabus: The JEE Main syllabus is similar to the one prescribed by CBSE whereas JEE-Advanced has a different syllabus. Various topics covered in JEE Main are not included in JEE Advanced. Eligibility: A good JEE Main rank will open doors for admission to NITs and IITs. But with a good JEE Advanced rank, one can get admitted into the most coveted IITs. Qualification: JEE Main required a student to have completed his Class 12th only. Whereas JEE Advanced has set certain minimum cutoff criteria in JEE Main and also meets minimum board exam criteria. Examination pattern: JEE Main exam comprises one paper only while JEE Main comprises 2 papers. The former consists of objective and single-answer questions while the latter consists of a variety of problems including multi-right, matrix match, comprehension types, and much more. The pattern of the former hardly changes while the pattern of the latter is modified every year. I hope such a detailed comparison has cleared your doubts and clarified the doubts regarding both the entrance exams. Read more

Ans. IIT Delhi has set papers twice in 2012 and 2013. However, there is no fixed level of difficulty for this exam as the final paper is not set by a single IIT. Rather, it is assembled after the inputs of eminent professors and experts of all IITs. First, a mixed team of professors from different IITs is formed by the concerned IIT The entire team is made to stay in one place in individual rooms. Professors will be given time and material to formulate questions Whenever they have formulated one or more questions, they will go to a highly secure room and write down the question This process is repeated till multiple sets of Physics Chemistry and Maths are ready. These sets are then submitted to the team leader who vocoders the final set of paper This is how a JEE paper is set and thus predicting the level of difficulty is almost impossible since it’s the work of multiple experts.
