Another problem that fracking causes is the damage that occurs when the pressurized water breaks through the ground. This is said to be a factor in the earthquakes that have been recorded. “The fracking process uses high-pressure injections of fluid to break apart rock and release trapped oil and natural gas. Both fracking and wastewater injections can increase the fluid pressure in the natural pores and fractures in rock, or change the state of stress on existing faults, to produce earthquakes.”

The Literature Review The earliest documented use of aromatic oils goes back as far as 4500 B.C.E. in Egypt.

The purpose of the lab was to make observations and inferences, on how 2 types of packing material reacts to different liquids. In part one of the lab, 2 different types of packing material was placed in separate beakers of acetone and water. After a minute of stirring using the glass stirring rod, iodine, an indicator, was added to each beaker. In part 2, tin foil was rolled and placed in a solution of water and crystals. Observations were taken in all parts of the lab. In part 1 of the lab, Peanut

Introduction Now, if you talk of rich men there is one man whose name you cannot exclude from the list. That person’s name is Raj Rameshwaran. He owns half of the city Mumbai. He had found a huge diamond mine in his house. He had used that money that he got from his diamond selling to start a business of selling chemical weapons. Now you will ask me how a diamond mine can be so huge that it could start a business of selling chemicals entirely out of it. By diamond mine I am talking

Identifying an unknown substance can be accomplished with the use of multiple scientific tests, which help narrow down the possibilities of the unknown compound. The unknown substance that I was given was unknown number A84841BIR, and posed to be a real challenge since I needed to test two different molecular combinations for this specific substance. Once the number of moles in substance was calculated using the ideal gas law, I divided it from the sample mass number after heating and obtained that

Purpose: The purpose of this lab is to identify the dyes present in the different mixtures. Introduction: This lab uses chromatography to determine the dyes present. It is also used to identify the different intermolecular forces each solution and dye has. Pre-Lab Questions: 1. 2. Rf = 2.8cm / 5.8cm = 0.50 3. Sample C is a mixture of Sample A and Sample B. 4. The intermolecular forces between Sample A and the solvent are stronger than those between Sample B and the solvent. Results: There

mixtures are heterogeneous and homogeneous. A heterogeneous mixture is a mixture that does not appear the same throughout. A homogeneous mixture is a mixture that is identical everywhere. A mixture could be composed of elements and compounds; both are pure substances. A compound is when multiple elements are put together, like water. Everything has chemical and physical characteristics and these qualities help scientists classify matter. Hypothesis If the properties are identified and utilized, then the
