Blog 9,2: LeChatelier's Principle

1. The system shifted to the right, so more of the heat energy went to the product.

3a. It is insoluble.
  b. A precipitate was formed and the solution became cloudy.
  c. The system shifted to the left, because the concentration of AgNO3 increased. The solution turned from purple to pink.

5. Since the color became darker, it indicates a shift to the right.

6. As soon as the bottle is opened, all of the pressure is released because it isn't a closed system anymore.

Enrichment

1. Chickens pant out CO2 gas.
2. When the CO2 decreases, the equilibrium shifts to the right.
3, It decreases.
4. Panting results in thinner eggshells because all of the CO2 that could be used to make eggshells was used for panting.
5. They could give the chickens carbonated water. This changes the equilibrium so it shifts to the left, giving the chickens stronger eggshells.
