Calculate ΔHrxnΔHrxn for the following reaction: 3C(s)+4H2(g)→C3H8(l)3C(s)+4H2(g)→C3 H8(l) Use the following reactions and given ΔHΔH values: C3H8(l)+5O2(g)→3CO2(g)+4H2O(g),ΔHC( s)+O2(g)→CO2(g),ΔH2H2(g)+O2(g)→2H2O (g),ΔH===−2026.6kJ−393.5kJ−483.5kJ
Answers: 1
for the reaction is -120.9 kJ.
( × 3)
( × 2)![\Delta H^o_{rxn}=[1\times (-\Delta H_1)]+[3\times \Delta H_2]+[2\times \Delta H_3]](/tpl/images/0548/9833/b4dbe.png)
![\Delta H^o_{rxn}=[(1\times -(-2026.6))+(3\times (-393.5))+(2\times (-483.5))]=-120.9kJ](/tpl/images/0548/9833/4ea2a.png)

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
