Organic Chemistry is one of the most important and scoring subjects in the ISC Class 12 curriculum. However, many students find it challenging due to its complex reactions, mechanisms, and vast amount of theory. In the last days leading up to the exams, it’s important to focus on key concepts, strategies, and efficient revision techniques…
One mole ammonium dichromate when heated decompose to form one mole of chromic oxide, one mole of nitrogen and four moles of water. (NH4)2Cr2O7 → Cr2O3 + N2 + 4H2O
Dinitrogen is prepared in the laboratory by heating a solution an equivalent amount of sodium nitrite and ammonium chloride when ammonium nitrite and sodium chloride are formed. Ammonium nitrite then decomposes to nitrogen and water. NH4Cl + NaNO2 → NH4NO2 + NaCl NH4NO2 → N2 + 2H2O
One mole of calcium phosphide reacts with six moles of water to form two moles of phosphine and three moles of calcium hydroxide. Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3
One mole of magnesium nitride reacts with six moles of water to form two moles of ammonia and three moles of magnesium hydroxide. Mg3N2 + 6H2O → 3Mg(OH)2 + 2NH3
Four moles of phosphorous acid decompose to form three moles of phosphoric acid and one mole of phosphine. 4H3PO3 → 3H3PO4 + PH3
Three moles of nitrous acid decompose to form one mole of nitric acid, two moles of nitric oxide and one mole of water. 3HNO2 → HNO3 + 2NO + H2O
What is an atom? An atom is the basic building block of matter, consisting of a nucleus containing protons and neutrons, surrounded by a cloud of electrons. Atoms are the smallest units of an element that still retain the properties of that element. Key components of an atom include: Nucleus: The nucleus is located at…
What is Henry’s law? Henry’s law describes the relationship between the pressure of a gas and its solubility in a liquid. It states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Mathematically, it can be represented as: C=k⋅P Where: C is…
Chemical kinetics, a branch of chemistry concerned with the rates of chemical reactions and the factors that influence them, holds significant importance in the JEE (Joint Entrance Examination) Main and Advanced Chemistry syllabi. Understanding the principles of chemical kinetics is essential for predicting reaction rates, elucidating reaction mechanisms, and designing efficient chemical processes. In this…
