Stressing Out Equilibruim Le Chatelier's Principle

1. When we added HCl to the system and heated it up, the system shifted to the right because the heat was on the reactants side.
2. When Delta H is negative it indicate a Exothermic Reaction, When Delta H is positive is indicate an Endothermic reaction.
3. Table F says that when Cl -1 ion is combined with Ag +1 ion it forms an insoluble compounds.

• Since Cl reacts which Ag with is part of AgNo3, it pulled out the reaction and made the reaction shift to the left.
• By adding AgNo3 we increased the ion concentration of No3 and we predicted that the system was going to shift to the right but it eventually shifted to the left.

Station Three Processing Questions:

When the system is closed, the solution is at equilibrium which means that the system is going back and forward and the pressure is increasing  and there's no formation of bubbles because they end up shrinking. But when you open the system,the amount of pressure decrease and the bubble appear bigger because gas is being released.

Questions:

• What gas do chickens pant out?

The chickens pant out Carbon Dioxide.

• When the [CO2]  decreases, which way does equilibrium shift?

Equilibrium shift to the right.

• When the equilibrium shifts, what happens to the amount of the CaCo3(s) ( the egg shell) that's is produced?

The egg shells are stronger.

• Explain why panting results in thinner egg shells.

When the chicken pants, the equilibrium is perturbed by the rapid loss of carbon dioxide. Because this effect cascades through all of these equilibria, the effect is a loss of solid calcium carbonate, which ultimately produces  weaker egg shells.

• What change could farmers make to assure thicker egg shells in hot water? How does this change take advantage of Le Chatelier's principle?

Farmers should make their chickens lay eggs inside in hot weather so that the sun will not easily or frequently    be broken. It will takes advantage of Le Chantelier's  principle because the equilibrium will be disturb.

Blog 9.1 Heat Of Fusion ( Delta H) Using Table I

1. My solution was Endothermic because the water got cold, so the energy flew from the air to the water with the solution.

2. The Possible source of errors could have been that the water got so hot that some evaporated, so since some evaporated it probably affected the mass.

3. If the room temperature was 10degree colder, i don't think i was going to affected the number of moles because the water wasn't going to evaporated which would keep the mass the same.

    Enrichment:

   Farmers spray water on the oranges so they can freeze them to prevent damage. When water freeze it turns into ice, heat is released through the heat of fusion. A gallon of water releases about 300kcal of heat as it freezes. However water is also evaporating in the atmosphere.The evaporation of water cause a loss of about 2,300kcal per gallon of water evaporated. Therefore to provide heat to the orchard, more water must freeze than evaporates.So 7.5 times water must freeze more than that which evaporates.
