Mineral 2:GRAPHITE
Things you might include: What is its chemical formula? Does it react to hydrochloric acid, HCl, by forming bubbles in HCl? You also might include if the rock or mineral is magnetic.
You may use bullet points or complete sentences.
If you use complete sentences, remember to use capitalization and punctuation, good grammar and spelling, etc.

Chemical Properties of Graphite

  • Chemical Formula: The chemical formula for graphite is C, which indicates that it is composed entirely of carbon atoms.

  • Reactivity with Hydrochloric Acid (HCl): Graphite does not react with hydrochloric acid (HCl) and does not produce any bubbles when placed in HCl. This indicates that graphite is chemically inert in the presence of strong acids.

  • Magnetic Properties: Graphite is not magnetic. It does not exhibit any magnetic properties and will not be attracted to magnets.

  • Electrical Conductivity: Graphite is a good conductor of electricity due to the mobility of its delocalized electrons within its layered structure.

  • Thermal Stability: Graphite has high thermal stability and can withstand significant temperatures without decomposing, making it useful in high-temperature applications.

  • Lubricating Properties: Due to its layered structure, graphite has excellent lubricating properties, allowing it to reduce friction between surfaces.
