Amedeo Avogadro was an Italian mathematician in the middle 1800’s. He devised a way of measuring the concentration of particles in a sample. Whether the sample is composed of atoms or molecules‚ he determined that the number of particles having a mass number matching the “atomic weight” was always 6.02 X 1023. In other words‚ if you had a sample of carbon with a mass of 12.011 grams‚ then you would have an Avogadro number of atoms. If you had a sample of water with a mass of 18.00 grams‚ then you

My results are consistent with those‚ conducted by Dr. Antonini who used the same type of welding fume particles (MMAW: manual metal arc welding). However‚ welding fume doses at 10 mg/kg and 20 mg/kg in my experiment were twice and 4 times‚ respectively‚ the dose that was used in Dr. Antonini’s paper [6]. In blood‚ Dr. Antonini found a 1.5-fold increase in Mn levels‚ whereas in my experiment I found an 8-fold increase in blood Mn after the 20 mg/kg dose. Both results are consistent since the 20 mg/kg

CHEM 17 Expt.2-Coupled Reactions 4/18/12 Results and Discussions: One way to obtain products from a non-spontaneous process that is exhibited in this experiment is by “coupling” two reactions. The principle of Coupled Reactions is based on a simple concept: we can use a thermodynamically favorable (spontaneous) reaction to drive an unfavorable one. One step is allowed to supply enough free energy for the other to occur. A coupled reaction is a system wherein a non-spontaneous

Environmental Action Plan Tree Plantation Project (TPP) They are cutting down more trees every day. By organizing a Tree Plantation Project (TPP) we can plant more trees that produce our oxygen. I will be working with the Schools and the Communities to educate how trees help cleanse the air by intercepting airborne particles‚ reducing heat‚ and absorbing such pollutants as carbon monoxide‚ sulfur dioxide‚ and nitrogen dioxide‚ and daily environmental activities. The current problems

llo 13 [pic] Apollo 13 Problem Solving Using SPICES 1. What situation is the movie Apollo 13 about? They want to go to the moon and land on it. 2. What was the big problem that happened during the movie? There isn’t enough power to come back to Earth. This is the big problem because all the other problems branch of from this issue. 3. List three smaller problems that also came up in the process of trying to fix the big problem. They can’t land on the moon‚ because they were

Tree Plantations Introduction For over 10‚000 years‚ man has been the greatest factor affecting biodiversity through habitat destruction and fragmentation‚ overexploitation and pollution. With an ever increasing population and human activities‚ man is consuming more and more natural resources by increasing the use of energy‚ fuel‚ and production of consumer products that are not necessarily needed. Man is very egotistic and believes that he owns everything that he has discovered; using most

How do we save our natural resources? How do we show the younger generation that we wanted to save the world now? We need to show that we are saving our natural resources for the next generation and save the future of our planet we love so much. Do we love this planet enough to save it? What do you think of when we say save the planet? When we hear this we think of tree hugging people who want to do nothing more than tell us that we need to protect the trees. Well when we hear save the planet we
