Potassium Phthalate, KC8H604, is a main source of whistle fuel for many fireworks. A standard firework had 25g of potassium phthalate.

Explanation:

The given compound is:

           KC₈H₆O₄

Mass of the compound = 25g

Molar mass of the compound

KC₈H₆O₄

   Atomic mass of K  = 39

                             C  = 12

                             H = 1

                             O = 16

Molar mass of the compound  = 39 + 8(12) + 6 (1) + 4(16)

                                                   = 205g/mol

Number of molecules of fuel there in:

Find the number of moles then convert this to number of molecules;

    Number of moles  =  

    Number of moles  =   = 0.12mol

1 mole of a compound contains 6.02 x 10²³ molecules

 0.12 mole of the phthalate will contain 0.12 x 6.02 x 10²³ =

              7.34 x 10²²molecules

Number of moles of Carbon

  1 mole of the phthalate contains 8 mole of carbon

  0.12 mole of the phthalate will contain 0.12 x  8  = 0.96mole of carbon

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
