Experiment 1: The Effects of Coal Mining Coal mining‚ particularly surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise
