The equation 2Ca + O2 -> 2CaO

  1. Detailed information about the equation 2Ca + O2 -> 2CaO:

    • Two molecules of calcium (Ca) react with one molecule of oxygen (O2) to form two molecules of calcium oxide (CaO).
    • Calcium and oxygen are chemical elements while calcium oxide is a chemical compound.
    • This reaction is a combination reaction, meaning the reactants combine to form a new compound.

  2. Reaction conditions:

    • The reaction typically occurs at high temperatures.
    • Calcium needs to come into direct contact with oxygen.

  3. Reaction process:

    • When calcium is heated in air or oxygen, it forms calcium oxide.
    • The reaction process will continue until one of the reactants is exhausted.

  4. Phenomena that occur:

    • During the reaction process, calcium will burn brightly in air or oxygen to form calcium oxide.
    • The product formed is a white, odorless, tasteless solid.
