How to Trick Your Brain Into Loving Study Sessions (Seriously)

Studying doesn’t have to feel like a slog. The truth is: your brain isn’t built to drag through hours of tedium—it responds best to pattern, reward and rhythm. By shifting how you approach study time, you can turn it from duty into something your brain actually enjoys. ‎Here are five simple, smart ways to do it. Try one today and see how your focus follows. ‎1. Study in Short Bursts, Not Endless Sessions    ‎Forget the idea that you must sit for three hours straight. Cognitive science shows our attention drops significantly after about 25–30 minutes. So use the Pomodoro Technique : study for 25 minutes, take a 5‑minute break; after four rounds, give yourself a longer break (15–20 minutes). That rhythm gives your brain permission to reset—and makes that “next block” easier to start.  ‎2. Turn Learning into a Game ‎The brain loves victory—even tiny ones. Set fun micro‑challenges: finish chapter one in 20 minutes, get 10 questions right in a row, or beat yesterday’s time. E...

How to Analylse the ions in Copper ( II) tetraoxosulphate VI)

  Copper   tetraoxosulphate VI is   a blue crystal solid if it contains water of crystallization(copper(II)tetraoxosulphate VI pentahydrate,CuSO 4 .5H 2 O). The anhydrous form is white. Copper(II)tetraoxosulphate VI is electrovalent compound and it is one of the soluble compounds of copper.         Tests for Copper(II) tetraoxosulphate VI In qualitative analysis of any compound or substance, the basic idea is to identify the ions in the compound. That means, one has to know the unique reactions of compound which contains any of the ions to be analyzed, for example all chlorides react with acidified silver trioxonitrate to form white precipitate which is soluble in ammonia solution.   In the case of copper (II)tetraoxosulphate VI, the two ions are copper ion,Cu 2+ and   tetraoxosulphate VI ion or radical,SO 4 2- .These two ions have some unique reactions which differentiate them from other ions. How to Test for Copper ion in an unknow...

Mole, Molar mass and Molar Volume

                                                                                                              Mole A mole of any substance is the amount of that substance which contains many elementary particles as the number of atoms in 12 grams of carbon -12. These elementary particles can be atoms, ions, electrons, molecules etc. A mole is a unit used in measuring the amount of particles.     The number of particles in one mole of any substance is equal to 6.02 x 10 23 . This number is also known as Avogadro’s number.        Molar Mass This is the mass of one mole of any substance expressed in grams. It is also the formula mass which is the sum of all atomic mass...

Qualitative Analysis of Ammonium Trioxocarbonate (IV)

              Ammonium trioxocarbonate(IV) is an electrovalent compound just like any other ammonium salts. As an electrovalent compound, it has NH + (ammonium ion) as the cation and CO 3 2- (trioxocarbonate IV ion or radical) as the anion.                          (NH 4 ) 2 CO 3   -------    2NH 4 + + CO 3 2- Ammonium trioxocarbonate IV is a white crystal salt and it is very soluble in water like all other ammonium salts. It decomposes on heating to produce ammonium, water and carbon (IV)oxide.                      (NH 4 + ) 2 CO 3   ----------   2NH 3(g) + H 2 O (I) + CO 2(g)          Test for the Cation in Ammonium Trioxocarbonate IV To test...
