Is there suppose to be a diagram attached to this?
Answer:
−2399.33 kJ
Explanation:
If NH₄NO₃ reacts with fuel oil to give a ΔH of -7198 for every 3 moles of NH₄NO₃
What is the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction
∴ For every 1 mole, we will have
of the total enthaply of the 3 moles
so, to determine the 1 mole; we have:

= −2399.33 kJ
∴ the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction = −2399.33 kJ
Answer:
84.2mL
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 128mL
Initial pressure (P1) = 500mmHg
Final pressure (P2) = stp = 760mmHg
Final volume (V2) =..?
Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
500 x 128 = 760 x V2
Divide both side by 760
V2 = (500 x 128)/760
V2 = 84.2mL
Therefore, the new volume of the gas is 84.2mL
