This is definitely one book that help shaped how we look at the environment today and also how we approach it. Rachel Carson aimed for a book that was going to open peoples eyes to what really was happening and who and what was doing it. She nailed this right on the head‚ while the book was very technical when it came to talking about the details of

Juliana Amenta 2/18/13 Mr. Zastrow Chemical Warfare During World War 1 The first World War has been reported to be one of the most brutal wars in the history of time for many reasons. One of those reasons was strategic usage of chemical warfare. Chemical gas was used on both sides of the line‚ which turned out to be fatal for many. World War I was mostly fought in the trenches‚ where soldiers lived in deep‚ v-shaped holes or underground bunkers. Both sides would occupy these trenches in order

There are many different ingredients in a kitchen that causes a chemical reaction with baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct

Physical and Chemical Reactions Lab #4 Alesa Cannon Objective: To investigate the physical and chemical properties of a pure chemical substance. Procedure: 1. Half-fill one well of a 24-well plate with 6 M HCl and half-fill a second well of the 24-well plate with 6 M NaOH. Suck up these chemicals into their labeled pipets for later use. 2. Perform the following steps on each of the substances to be tested. Complete all tests of one substance and record your observations before proceeding

3.1.1 Identify that matter is made of particles that are continuously moving and interacting The particle theory states that all matter is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds

Heavy Machinery is the prime need of the industries. The machines like bulldozer‚ Skid Steer Machinery‚ excavator‚ wheel loaders‚ drilling machine‚ mixer trucks and many more are used for the construction purposes‚ while the cranes‚ industrial truck‚ forklift and other such machines come in use in the production industry. Therefore‚ it is always recommended to use good machine that generate necessary power and also gets the work done. To buy these typical machines is not an easy task as they are

Chemical reactions proceeding until all the reactants are used is a common misconception. Chemical reactions actually behave differently. The general reaction equation is a A + b B → c C +d D in this equation A and B are the reactants forming the products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b
