Submitted: June 10‚ 2015 Title: Observations of Chemical and Physical Changes Purpose: the purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals with different background to see if there was a chemical

Chilean Copper Mine Collapse BCOM/275 4/14/14 Randall Savely August 5 2010‚ 33 miners were trapped 2400 feet underground in a northern Chilean copper mine. For 17 days there was no way of knowing if any of the miners were still alive. A drill sent down by a rescuer came back with a message from the workers notifying them that they were all alive‚ but limiting in supplies. Rescuers then planned on sending supplies‚ such as‚ food‚ water‚ medicines‚ etc‚ expecting several

Pre Lab 1a. Hydrated compound: ionic compound which contain water molecules inside their crystal lattice. The water is not chemically bonded to the crystal in any way and can be extracted by heating the compound. 1b. Anhydrous compound: a compound without water. 2a. The dot means that there are water molecules present in the crystal lattice in a specific ratio. 2b. For every mole of copper sulfate‚ there are five moles of water. 2c. The molar mass of copper (II) sulfate is 159.61 grams/mol
