P4O6(s) + 2O2(g) P4O10(s)
round to the nearest whole number
(help please its stressing me out to the max)

2 Answer

  • If you're just looking to balance you equation then it's already balanced. I don't know what our mean by "round to he nearest while number" there will always be a whole number of atoms
  • Answer:

    Consider the chemical equations shown here.

    P4(s) + 3O2(g) → P4O6(s)   ΔH1 = -1,640.1 kJ

    P4O10(s) → P4(s) + 5O2(g)   ΔH2 = 2,940.1 kJ

    What is the overall enthalpy of reaction for the equation shown below?

    Round the answer to the nearest whole number.

    P4O6(s) + 2O2(g) Right arrow. P4O10(s)

    Answer:  -1300
