Blog 9.1 Heat of Solution

Blog questions:
1. The Solution was endothermic because heat was absorbed, and the substance felt coder after the reaction.
2. The percent error for my experiment was 12%.
3. Possible sources of error were not exactly calculating 50 mL of water, or measuring too much or too little NH4Cl..
4a. The change would have been greater because some of the heat would have been lost to the surrounding air, and the total amount of heat lost would be greater
4b. The change would be less substantial because the concentration would be lower.
4c. The percent error would have been greater because the molarity would be greater.

Enrichment:
This is done to prevent cold temperature from damaging the oranges. When the trees are sprayed, the water will eventually freeze, ad absorb the harmful heat before the fruit is affected.
