Question 11 11 point)
A blacksmith has a small furnace which outputs 5,000 joules of heat energy. A piece of iron starts at room temperature, 25.0"C and is raised to
the max temp of the furnace, 500°C. What is the mass of the plece of iron that the blacksmith can work with (Figure out what equation to use
and write down as much work as possible so I can give you partial credit. You will need he thermochemistry equation constant sheet)

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?
