How will solving This Dedicated Chapter by Chapter Problems boost the Student’s Score?

With a vast syllabus like that of the JEE Advanced, students have no choice but to smartly break it down subject-wise and then even further ahead, in two different modules and chapters in order to get a clear picture of what they are about to study and create a plan for the same. Now, even after having completed studying the entire portion, it is very important that students pay as much attention to solving the important questions of individual chapters as they are to solving a paper based on the whole syllabus.

This will help them identify the areas where they need improvement, as well as the things that they can do in order to improve the speed of solving the questions. Thus even after fully completing the syllabus students must not only focus on solving papers based on the whole syllabus but also equally pay attention to important questions based on individual chapters.

Things to Note While Solving These Questions:

Students must understand that they shouldn't just randomly start solving these important questions given in the document, but rather try and create the right atmosphere around them before solving. Many students tend to make mistakes while solving these problems purely because of the fact that they are taking it casually and not as though they are appearing for the final exam. Thus a change in attitude is required where they attempt every single question with all they've got and with sincerity. They can also ask their parents to act as supervisors just to ensure that they do not take frequent breaks or refer to any reference material while solving these questions.

Chemistry is a vast and volatile subject. If you are confused as to where you need to start, here are a few topics from the syllabus that can help you to kick start your study process.  

  • Mole

  • Avogadro’s number

  • Law of conservation of mass

  • Law of definite proportion

  • Law of multiple proportions

  • Law of gaseous volume

  • Average atomic mass

  • Molecular mass

  • Empirical formula

  • Molecular formula

  • Mass percentage

  • Mole fraction

  • Molarity

  • Molality and Normality

  • Numericals

  • Formulae

Some Basic Concepts of Chemistry JEE Advanced Important Questions – Advantages

JEE is an extremely intense competitive exam. It needs consistency and hard work from students in order to crack it with flying colours. Solving the JEE Advanced Some Basic Concepts of Chemistry Important Questions allows you to learn to solve questions with utmost accuracy even under the stressful conditions of exams. These questions and answers are very reliable study material for those hoping to get high marks in the exam.

FAQs on JEE Advanced Some Basic Concepts of Chemistry Important Questions

1. With reference from Some Basic Concepts of Chemistry, what is a redox reaction?

A reaction in which an element bonds with oxygen, breaks its bond with Hydrogen, or one that takes place with ‘loss of electrons’ is known as an Oxidation Reaction. On the other hand, a reaction that occurs with an element bonding with Hydrogen, breaking its bond with oxygen or one that takes place with ‘gain of one or more electrons’ counts as a reduction reaction. Naturally, a reaction in which both Oxidation and Reduction takes place simultaneously is known as an Oxidation-Reduction or simply a Redox reaction. The molecule that gets oxidized is known as the reducing agent and the one that gets reduced is the oxidising agent.

2. Explain the concept of limiting reagents in brief with reference from Some Basic Concepts of Chemistry.

Let us tackle this with a real-world example. Say you’ve got to make coffee and you’re told that every cup of coffee requires 1 spoon of coffee powder, 2 spoons of sugar and half a glass of milk. Now you notice that you have a lot of sugar, lots of milk at home, but only 4 spoons worth of coffee powder. You will soon understand that you can only really make a maximum of 4 cups of coffee, regardless of how much excess sugar or milk you have. The coffee powder, in this case, acts as an example of a limiting factor, which sort of “limits” the maximum product you can obtain from the given materials. In chemistry, these are called limiting reagents and one of the reactants in a chemical reaction acts like one.

3. With reference to concepts from Some Basic Concepts of Chemistry, what is the value of the Avogadro number and what counts as a mole?

A mole is something that contains 6.022 X 1023 of any chemical entity, that entity being atoms, molecules, ions or others. The number 6.022 X 1023 is known as the Avogadro number based on the Italian scientist, Amedeo Avogadro. The mole is often used as the standard chemical unit in order to quantify chemical substances. The mole also was previously defined as the number of atoms experimentally determined to be found in 12 grams of the Carbon-12 atom. This definition was later modified in and the one in use today is mentioned above.

4. What is the difference between Molality, Molarity and Normality with reference to Some Basic Concepts of Chemistry?

All the three are nothing but different units of concentration used based on the situation. Considering how similar all these words look, it might be confusing for students to remember what each of them means. Let’s define each of them as simply as possible.

  1. Molality: Denoted by ‘m’, it is calculated as the number of moles of solute present in 1 kilogram of solvent.

    Formula: Molality (m) = \[\frac{Take\: Moles\: of\: Solute}{Total\: Kilograms\: of\: Solvent}\]

  1. Molarity: Denoted by ‘M’, it is defined as the number of moles of solute, divided by the total volume (in litres) of the solution

    Formula: Molarity (M) = \[\frac{Total\: Moles\: of\: Solute}{Total\: Litres\: of\: Solution}\]

  1. Normality: Denoted by ‘N’, normality is just another ratio that relates the number of equivalents that exists per litre of the solution

    Formula: Normality (N) = \[\frac{Number\: of\: equivalents}{1\: L\: of\: the\: Solution}\]

5. With reference from Some Basic Concepts of Chemistry, what are some important points to note about Le Chatelier’s Principles on equilibrium?

The Le-chatelier’s principle is basically an observation about chemical equilibria and the factors that lead to it, influence it, disturb it, etc. The points worth noting down about Le-Chatelier’s principles are as follows:

  • Used to predict the behaviour of a system in equilibrium when changes in temperature, pressure, or concentration are introduced.

  • The addition of heat in a chemical reaction at equilibrium will favour the endothermic direction of the reaction, and the opposite is true for the removal of heat.

  • An increase in the concentration of reactants will drive the equilibrium to the right, whereas a decrease in the concentration will drive the equilibrium to the left.

That pretty much wraps it up from our side and we really hope you found this article of some use. Students preparing for the JEE advanced and wanting to secure a seat in one of the prestigious IITs must daily focus on preparing all three subjects equally well and this won't come without constant efforts, revision and practice. 

We recommend students solve such important questions on a regular basis so as to ensure that they don't forget or lose touch with the formulas and important concepts that they have learnt over the past two years. Not just for this chapter but Vedantu has you covered from nearly all fronts by providing dedicated articles for every single chapter in your syllabus. We wish every aspirant the best of luck in their preparation as well as for their final exam! Students can get access to all the important questions and topics from the website of Vedantu. The student can visit the website and download the study materials in the PDF format for free from the app and website.
