Answer:
ΔH°_rxn = -195.9 kJ·mol⁻¹
Explanation:
4NH₃(g) + 3O₂(g) ⟶ 2N₂(g) +6H₂O(g)
ΔH°_f/(kJ·mol⁻¹): -45.9 0 0 -241.8
The formula relating ΔH°_rxn and enthalpies of formation (ΔH°_f) is
ΔH°_rxn = ΣΔH°_f(products) – ΣΔH°_f(reactants)
ΣΔH°_f(products) = -6(241.8) = -1450.8 kJ
ΣΔH°_f(reactants) = -4(45.9) = -183.6 kJ
ΔH°_rxn = (-1450.8 + 183.6) kJ = -1267.2 kJ
Answer:
false
Explanation:
The atom model has changed over time because of the discovery of subatomic particles
<span>Each liquid boils only at a certain temperature, which is called its </span><span>Boiling Point
Water for example has a boiling point of 100 degrees Celsius.</span>
Condensation goes with A.
Evaporation goes with C.
Sublimation goes with B.
Freezing goes with D.
Answer:
its endothermic .
because your using a cooling process instead of a heating process if it was a heating process it would be exothermic
