• What are Alkanes?

  Hydrocarbons are carbon-containing compounds. They are organic compounds that contain C-C and C-H bonds.

• What is a Solution?

  A solution is a homogeneous mixture formed when a solute, typically present in smaller amounts, dissolves in a solvent. Solutions can vary based on the physical states of the solute and solvent, leading to liquid, solid, and gaseous solutions.

• How to Determine the Limiting Reagent in a Chemical Reaction?

  The limiting reagent, is consumed first during the reaction. It is termed “limiting” because it limits the extent of the reaction.

• How to Convert Between Moles and Grams?

  In the world of chemistry, the ability to convert between moles and grams is a fundamental skill for chemical calculations and analyses.

• What is The Mole and How Many Atoms are There in One Mole?

  In the laboratory, we need a unit that can be used for practical measurements. For this purpose, we use the unit mole, which can later be converted to grams. The mole is a unit of measurement that is used to count the number of atoms, molecules, or ions in a substance. One mole of any…

• How to Calculate Average Atomic Mass?

  The mass of atoms depends on the number of protons, electrons and neutrons they contain. As atoms are extremely small, it is impossible to weight them using normal units.

• Chemistry of Perfumes

  Compounds that are responsible for fragrance: Essential oils and aroma chemicals. Components responsible for applying perfumes: solvents/base, carrier oils, fixatives, solubilizers and accents and additives

• The difference Between the Electrophilic and Nucleophilic Addition Reactions

  Learn The difference Between the Electrophilic and Nucleophilic Addition Reactions. The electrophilic addition happens when our organic compound contains a double bond. The nucleophilic addition reaction happens with compounds containing polar bonds, such as carbonyl bond.

• Balance redox equations (reaction of copper with potassium permanganate)

  Learn balance redox equations (reaction of copper with potassium permanganate). Copper reacts with potassium permanganate is an example of redox reaction in which copper oxidation state changes from zero to +2.

• Iodoform test

  Iodoform test is used to test for the presence of either methyl ketone group CH3CO or secondary alcohol CH3CHOH.  In the iodoform test, sodium hydroxide is added to iodine pellets after the dissolve of iodine in sodium hydroxide the aldehyde or ketone is added.

• Empirical formula

  Empirical formula

• Molecular Formula

  Chemists express the composition of molecules using chemical formulas. For example, we can represent the reaction of hydrogen with oxygen to give water molecules using symbols. Where hydrogen gas is H2, oxygen is O2 and H2O represents water.

• The Electrons and Cathode-Ray Tube

  The atom is the basic unit of any substance. The atom consists of three main components. Protons, neutrons, and electrons.

• Dalton’s Atomic Model

  Dalton revived Democritus postulation when he found that each time tin reacts with oxygen gas to give tin oxide they react with a ratio 1:2 (tin : oxygen). From that he assumed that each tin and oxygen must contain small particle that take a place in the chemical reaction.

• Calculating Lattice Energy For Al2O3

  Calculate the value for the lattice energy of aluminum oxide and energy diagram for aluminum oxide

• Infrared spectroscopy (FTIR)

  In Infrared spectroscopy (IR), a sample is placed in the direction of the infrared source when the infrared spectrum falls on the sample the molecules absorb certain frequencies corresponding to the characteristic structure of molecules, and peaks are observed.
