Stellar Energy: The Power of Nuclear Fusion

Stars are powered by nuclear reactions involving hydrogen (H) and helium (He).

The source of stellar energy is nuclear fusion: the combining of lighter nuclei into heavier ones. The immense amount of energy released is described by Einstein’s famous equation: E = mc2.

The greater the nuclear binding energy, the more stable the nucleus.

Conditions for Nuclear Fusion

Nuclear fusion only occurs at temperatures

Chemical Titration Methods: Complexometric & Precipitation Analysis

Complexometric Titrations

Complexometric titrations are a type of volumetric analysis involving titrants that form a soluble complex with the analyte (the substance being valued). In any complex, two main parts are distinguished: the central atom (usually a metal atom or ion) and the ligand.

Types of Ligands in Complexometric Titrations

  • Atomic or Molecular Ligands

    When the ligand is an atom or molecule, the resulting complex is often referred to as a coordination compound. For neutral ligands, the overall
