    Took the idea from Junior Certificate, I ask a question and you answer it and you then ask a question. Simples :D

    Also, state what subject relates to the question you are asking.

    Biology

    What is the definition for sex linkage?

    Where the gene for a trait are carried on the sex chromosomes. (Not correctly worded but i think its right!)

    Chemistry: Why is steam distillation used to extract clove oil from cloves?


  • Registered Users, Registered Users 2 Posts: 11 mnop


    Steam distillation allows the mixture of organic liquids to distill below 100 degrees which makes it good for unstable or high boiling point compounds. (Eugonol has a boiling point of 254 degrees)

    In the modern Table the elements are arranged in order of increasing atomic Number. In Mendeleev's, atomic weight.

    There are no gaps in the modern periodic table of elements.
    Mendeleev left gaps in his table for undiscovered elements.

    In the modern table the transition elements are listed seperately.
    Mendeleev did not put the transition elements in a seperate block.

    Actually Sunny, whats the answer to the one about molten ionic compounds and electriicity, I've never come across that before
    Physics people, describe how a fridge keeps things cold.

    it won't in the solid state as the particles are fixed.
    And the particles are not fixed in the molten or dissolved state:)

    I don't do chemistry so as far as the JC takes me I believe Marie Curie died from radioactivity and some lad called Becquerel(?) discovered it.
    I think it's got something to do with the decay of atoms.

    Btw love the idea! Maybe thread is a little chemistry heavy though ;-)

    Chemical equilibrium is where the rate of reactions for both sides of a reversible reaction are equal ie. the concentrations of reactions and products will not change for a fixed system.
    Dynamic equilibrium refers to equilibrium in which the two 'opposite' forces are equal and constantly acting against each other (effectively cancelling each others effect), thus causing an overall state of equilibrium.

  • Registered Users, Registered Users 2 Posts: 2,576 ✭✭✭Coeurdepirate


    (i) If an atom is supplied with energy it goes to a higher energy level and is called excited.
    (ii) The electron isn't stable in the higher level so it moves back down which releases energy.

    Prokaryotic cells do not have a nucleus or membrane enclosed organelles eg. Mitochondria.
    They are single celled organisms such as bacteria.
    They are small and primitive.

    Eukaryotic have enclosed nucleus and cell organelles.
    They are larger and more advanced.
    They are multi-cellular organisms eg. plant and animal.

    This is only a guess, but separation of masses of elements uses a magnetic field.
