    Question

    Which of the following gases were used in Urey-Miller’s experiment?

    1. Methane, carbon-di-oxide, ammonia, and water vapor
    2. Methane, hydrogen, ammonia, and water vapor
    3. Methane, hydrogen cyanide, ammonia, and water vapor
    4. Oxygen, carbon di-oxide, ammonia, and water vapor

    Hint:

    The Urey Muller experiment was a chemical experiment that demonstrates origin of life from the primitive condition of the earth

    The correct answer is: Methane, hydrogen, ammonia, and water vapor

      • Urey Muller experiment used water methane hydrogen and water.
      • They prepared the same condition as they thought the primitives earth would have.
      • Continuous ekectric sparks were fired to simulate the lightening in the water vapour and gaseous mixture 
      • The chemical reactions occurred that produced amino acids such as glycine and alanine
