Exam

The following are the key concepts of this chapter: Compound, Elements, Rules, Law of conservation of mass, Addition and Subtraction, Atomic Mass, Law of multiple proportions, and Molecular Mass.

As the name suggests, the first chapter of the NCERT Class 11 Chemistry introduces various basic concepts of chemistry, such as the definition and importance of chemistry, atomic matter and molecular masses, the mole concept, laws of chemical combination, empirical, stoichiometry, and molecular formulas. It also includes the concepts of molarity and molality.

The following are the real-world applications of electrochemistry - military applications such as thermal batteries, digital watches, hearing aids, digital cameras, electrical appliances such as cellphones, and torches.

It depends on students. Though it is not a tough chapter to study but for students who have misconceptions and those who struggle with visualization can find it challenging. 

There are two types of electrochemical cells - Electrolytic and Galvanic or Voltaic cells. The electrolytic cells need an external source such as AC power source or DC battery and it involve non-spontaneous reactions. The galvanic cells gets its energy from redox reactions which is spontaneous.

Redox reactions is the basic principle of the electrochemistry. The redox reactions is the process where electrons are transferred between substances. In this process chemical energy gets converted into electrical energy and vice versa.

The past year's NSI Admission Test have some important things to think about.

Getting to Know the Exam Format. Understanding the structure of the test and the types of questions and how difficult they are to answer is critical for test success. Students are often surprised and ill-prepared for how challenging and exhaustive the tests are. Knowing the level of difficulty beforehand can change and improve the outcomes of prospective candidates.

In simple words, the study of relationship between electrical energy and chemical reactions is called the Electrochemistry. The concept comprises how chemical reactions can create electrical energy and how electrical energy can generate chemical changes.

No. Since KEAM has transitioned to a computer-based test from 2024, hard copies of the question papers are not provided to the candidates. However, the KEAM question paper PDFs are uploaded on the official website of KEAM after the exam is over.

Solving past year papers of KEAM, has the following benefits:

1. Candidates get insights into the exam pattern and marking scheme.
2. Candidates can check the past years papers to identify the high-weightage topics.
3. They help the candidates improve their speed and accuracy.
