Respuesta :
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
