The Effects of Coal Mining 1. Develop hypotheses predicting the effect of pyrite and coal (activated carbon) on the acidity of water? a. Pyrite hypothesis = b. Coal (activated carbon) hypothesis = 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how .Effects of ionic liquid concentration on coal .1 INTRODUCTION Coal is likely to combust spontaneously in various stages such as mining, transportation, and storage. Coal spontaneous combustion (CSC) can not only produce lots of toxic and harmful gases, but also cause casualties. 1-4 Therefore, CSC prevention is of great significance for the safe production of coal. 5 Many methods have been proposed to inhibit CSC in underground coal .Theeffects of Coal Mining Essay - 1320 Words | AntiEssaysLab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining |Table 1: pH of Water Samples | |Water Sample |Initial pH |Final pH (24-48 hours) | |Pyrite |6 |7 | |Activated Carbon |6 |7 | |Water |6 |6 | NOTE: Picture below is after 48 hours of all three samples sitting in a warm place.Mussels Villosa iris (Unionidae) Effects of Coal Particles in Aquatic .et al. 2009); however, the sublethal effects of coal mining–related stressors on freshwater mussel organ tissues have yet to be studied.
