Problem: What methods could be used to extract materials from the given mixture that contains iron filings‚sand‚salt and small stones? Background There are things that must be understood before doing this lab. The first thing that must be understood is a mixture. A mixture has two or more pure substances‚ and the substances keep their chemical compositions (study.com).The next thing to apprehend is filteration. Filtration is a method used to separate a solid that isn’t dissolved in water. Another

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

Lab Safety Report By: CHM 114 Laboratory Fall 2014 Tuesday Lab 08/09/14 Splash Goggles: Safety is by far the most important thing when working in a chemical laboratory. There are over thousands of injuries that occur each year that are partially non-preventable‚ but a great majority are preventable accidents that could have been solved with simple lab safety. One of the most critical pieces of lab safety would have to be wearing eye protection. Eye protection could save your vision

In "Is Google Making Us Stupid?" Nicholas Carr argues his deep concern on the use of the Internet and how it is affecting our brains. Carr feels like he has built upon the habit of skimming through articles for research. As a frequent user he has built such a strong habit of this that he can now no longer have the patience to sit down and read an actual book. For it lacks the instant gratification he is so used to getting from the Internet: "What the net seems to be doing is chipping away from my
