### Energy Calculations

I am extremely confused with the energy's that correspond to that of the different structures of different compounds, how should we be able to verify which structure has more energy if they are both in the chair position?

### Stoichiometric Rates Discussion 1L Adam Perez

The formation of alumina, Al2O3, can be illustrated by the reaction below: 4 Al (s) + 3 O2 (g) ----> 2 Al2O3 (s). At 750 K it takes 267 seconds for the initial concentration of Al2O3 to increase from 6.18 E-5 M to 5.11 E-4 M. What is the rate of Al?

### Re: Post All Chemistry Jokes Here from Adam Perez Discussion 1L

A block of dry ice was sitting on a table and begins to turn into carbon dioxide gas. After a while, the block is gone and a cloud of CO2 is floating around. A nearby oxygen cloud asks, “Hey, I just saw you go through a phase change…how was it?”
The CO2 cloud replies, “It was sublime!”
