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...
In this second part, we are going to be looking at the stoichiometry of reaction involving the volume of gases. Just like what we saw in mass and mole, there is a relationship which also exists between mass and volume or mole and volume that is what we are going to look at. A close look at a balanced chemical equation shows the ratio in which the reactants react and the ratio in which the products are produced. However, an experiment has shown that at standard temperature and pressure, gases have an equal volume which is numerically equal to 22.4 dm 3 or 22400cm 3 . This volume is known as the molar volume of gases. 1mole of any gas at STP = 22.4dm 3 32g of oxygen at stp = 22.4dm 3 Let us consider the decomposition of potassium trioxochlorate (V) compound. 2KClO 3(s) ---------- 2KCl (s) + 3O 2(g) 2 moles of KClO 3 will decompose to give 2 moles of KCl and 3 moles of oxygen gas. Since the molar volume gas is 22.4dm...
