    1) P4O10

    2)I don't know

    3) Yes

    4) You must balance left to right side by the numbers in front and don't forget that 1(one) is also a number

    5) to much to explain

    6)12 moles and then I don't know what a skeleton is but you can use the balanced equation for the answer

    Hope this helps. Good luck
