Star ignites from fusion reactions
Ignition should not be confused with breakeven, a similar concept that compares the total energy being given off to the energy being used to heat the fuel. The key difference is that breakeven ignores losses to the surroundings, which do not contribute to heating the fuel, and thus are not able to make the reaction self-sustaining. Breakeven is an important goal in the fusion energy field, but ig… Webb26 nov. 2024 · Use the reactions here to determine the ΔH° for reaction (i): (ii) HCl(g) HCl(aq) ΔH ∘ ( ii) = − 74.8kJ (iii) H 2(g) + Cl 2(g) 2HCl(g) ΔH ∘ ( iii) = − 185 kJ (iv) AlCl 3(aq) AlCl 3(s) ΔH ∘ ( iv) = + 323kJ / mol (v) 2Al(s) + 6HCl(aq) 2AlCl 3(aq) + 3H 2(g) ΔH ∘ ( v) = − 1049kJ Answer
