Blog 9.2

1) When HCl was added, the solution turned dark blue and shifted to the right.
2)When looking for the delta H, you can determine if it is exothermic or endothermic by looking at table I, so if there is a negative sign in the amount of kJ that means that the reaction is exthermic, and when there is a plus sign, that indicates that it is a endothermic reaction. You can determine this by looking at a potential energy chart.
3) Table F says that when they react together they are insoluble.
When you add AgNO3, the reaction changed to a pink color and shifted to the left.

6) When the soda container was opened, the reaction shifts to the right since all the pressure from the closed can has been released and because the amount of CO2 is increasing inside of the can.

ENRICHMENT:
1) CO2
2) Shift to the right
3) The amount of CaCO3 decreases
4) The more panting results in a thinner shell because there is less CaCO3
5) Change the temp and this would take advantage of LeChateliers princple because you would be controlling the temp
