Diluting concentrated sulfuric acid with water can be dangerous. The temperature of the solution can increase rapidly. What are the signs of DH, DS, and DG for this process? a. DH< 0, DS > 0,DG< 0
b. DH< 0, DS < 0,DG< 0
c. DH< 0, DS > 0,DG> 0
d. DH> 0, DS > 0,DG< 0
e. DH> 0, DS < 0,DG> 0

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?
