Hello, guys.
00:02
We're doing problem number 42 in chemistry of central science, this chapter 5.
00:08
So if outferring to tables, they want to spread the higher enthalpy in four scenarios.
00:12
So broadly speaking, banking bond formation leads to lower entropy and bond breaking leads to higher enthalpy.
00:21
So we can apply that broadly.
00:31
So in part a, we're dealing with one mole of solid co2 and one mole of gase of co2.
00:39
Since cell at co2, the molecules are more closer together, so you're going to have stronger imfs, and gas is co2, the molecules are further ways.
00:48
You're going to have weaker imfs.
00:50
So that means that gas is co2 is going to have the higher end.
00:55
You have two hydrogen atoms and one mole of h2 gas.
01:01
Since you have to input energy to break h2 and form hydrogen atoms, then 8 atoms, this has h5, atoms are going to be less stable, and they're going to produce us, and you're going to have them producing a higher enthalpy than h2...
