Chapter 1 Real Number NCERT Solutions For Class 10 Maths – Click Here The topics and sub-topics in Chapter 1 Real Number is given below.
The world of real numbers and encountered irrational numbers. Here we know about the real number and the theorem used. 1.1 Introduction: NCERT Solutions For Class 10 Maths Chapter 1 Real Number 1.2 Euclid’s Division Lemma, (Euclid’s Division Lemma) : Given positive integers a and b, there exist unique integers q and r satisfying a = bq + r, 0 ≤ r < b. To obtain the HCF of two positive integers, say c and d, with c > d, follow the steps below: Step 1 : Apply Euclid’s division lemma, to c and d.
Step 2 : If r = 0, d is the HCF of c and d. Step 3 : Continue the process till the remainder is zero. This algorithm works because of HCF (c, d) = HCF (d, r) where the symbol HCF (c, d) denotes the HCF of c and d, etc. Example 1 : Use Euclid’s algorithm to find the HCF of 4052 and 12576. The remainder has now become zero, so our procedure stops. 1.6 Summary. NCERT Solutions For Class 10 Math Chapter 15 Probability. NCERT Solutions For Class 10 Math Chapter 15 Probability Types of Probability – Experimental ProbabilityTheoretical Probability Probabilities are based on the results of an actual experiment,that is why it is called as experimental or empirical probabilities. we defined the experimental or empirical probability P(E) of an event E as P(E) = Number of trials in which the event happened/Total number of trials The empirical interpretation of probability can be applied to every event associated with an experiment which can be repeated a large number of times.
Example 1 : Find the probability of getting a head when a coin is tossed once. Solution : In the experiment of tossing a coin once, the number of possible outcomes is two — Head (H) and Tail (T). P(E) = P (head) = Number of outcomes favourable to E/Number of all possible outcomes = 1/2 Similarly for Tail. Example 2 : A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. (i) yellow ball? Remarks :1. 3. NCERT Solutions.

Summary of Equilibrium Class XI part 1 chemistry question and answers Equilibrium is very important topic to study not only in chemistry but in numerous biological and environmental processes. To understand it better let’s take an example, equilibria involving Oxygen molecules and the protein haemoglobin play a crucial role in the transport and delivery of oxygen from our lungs to our muscles.
On the same way equilibria involving CO molecules and haemoglobin account for the toxicity. Equilibrium can be established for both physical processes and chemical reactions.

JEE Main -General Principles And Processes of Isolation of Elements- Important Question – JEE MAIN. Summary of General Principles And Processes of Isolation of Elements Chemistry class XII part 1 questions and answers In nature, elements occur in combined forms in the earth’s crust. A few elements occur in the free state, like carbon, sulphur, gold and noble gases. To extract the elements in a pure state, from its combined forms require various techniques and processes. In this case, the processes are known as metallurgy. In this topic, we learnt about extraction of metals from its ores. Occurrence of Metals Concentration of Ores Extraction of Crude metal from Concentration Ore Thermodynamic Principles of Metallurgy Electrochemical Principles of Metallurgy Oxidation Reduction Refining Hydraulic Washing Magnetic Separation Froth Floatation Method Leaching Uses of Aluminium, Copper, Zinc and Iron To learn about each topic in detail student can read ncert chemistry class XII part 1 textbook chapter General Principles and Processes of Isolation of Element.

Chapter Summary d and f-block elements Class XII part 1 chemistry Questions and Answers d-block elements are also known as transition metals. These are arranged from group 3-12, all these elements are placed in the centre of the periodic table. There are mainly three series of the transition metals, 3d series (Sc to Zn), 4d series (Y to Cd) and 5d series (La to Hg, omitting Ce to Lu). The fourth 6d series which begins with Ac is still incomplete. The two series of the inner transition metals, (4f and 5f) are known as lanthanoids and actinoids respectively.
The general electronic configuration of d -block elements is given by (n-1)d1-10 ns1-2. The (n-1) stands for the inner d orbitals which may have 1to 10 electrons and the outermost ns orbital may have one or two electrons. The f-block element consists of two series, lanthanoids (the fourteen elements following lanthanum) and actinoids (the fourteen elements following actinium).
D and f block elements is a chapter of class 12. Like this:
