POST LAB QUERIES
1 . Develop hypotheses guessing the effect of pyrite and coal around the acidity of water?
a. Pyrite hypothesis = it might contaminate normal water or dirt by increasing acidity amounts. b. Fossil fuel hypothesis sama dengan can cause a problem with subterranean mining because it can cause the river as well as the minds to be polluted. This may also increase the tempters and the ph.
2 . Based upon the effects of your test, would you deny or acknowledge each hypothesis that you produced in question you? Explain how you determined this.
a. Pyrite hypothesis accept/reject = My spouse and i accept my hypothesis as a result of all the acid that generates with the material used as well as the harm it makes to many areas b. Fossil fuel hypothesis accept/reject = I accept my personal hypothesis as a result of pollution and the minds happen to be being claps.
3. Based on your data, what effect do you predict coal mining has on the environment?
4. What can be done to prevent mine drainage from damaging the ecosystem? Utilize at least one academic resource to compliment your suggestions.
