Making Your Own Organic Shampoo Once you have chosen your castile soap base‚ you can add your essential and/or fragrance oils to the mixture. Different oils will affect the hair in different ways depending on what you are looking for in a homemade shampoo. For instance if you are looking to control dandruff and to sooth an itchy scalp‚ then you would add Tea Tree oil and Chamomile to your shampoo base. If you wanted to add extra shine to your hair with a great scent‚ then you would add Lemongrass

Notes on the history of the atom In 1897 the British physicist Joseph John (J. J.) Thomson (1856–1940) discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube‚ an area being investigated by numerous scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets as evidence of &quotbodies much smaller than atoms&quot that he calculated as having a very large value

getting warm and then they just disappeared. I heard some older water molecule calling it evaporation. I did not like the sound of it but I had to find my parents. My friend Zach agreed to help me. Today we were watching sharks attack a school of salmon when it happened‚ I felt weirdness. Everything started to warm up‚ like my parents had said. Zach felt it too. Looks like we were going to evaporate together. Other water molecule started to go up around us and then we were floating. Day 2 – Condensation-

Chemical Bonding and Structure In his essay I will be discussing the scientific background and explanation of chemical bonding and structure‚ I will also be describing the method of injection molding and its benefits and limitations and how it is superior to the previous methods of making plastic. Finally I will also list the implication effect of plastic and its effect (economically and environmentally) A chemical bond is the result of a lure (attraction) between atoms or ions

nuclear energy was linked to military purpose. The Atoms for Peace speech from Eisenhower in 1953 helped to change this point of view. In his speech he persuaded the world increase the researches within the nuclear power field with the focus on the energy possibilities‚ and start to decrease the potential destructive nuclear weapons. He shifted the focus from nuclear energy from war and fear to an open and peaceful way of generating energy (Atoms for Peace). The Dutch government already saw nuclear

Yvan Mamboukuate 10/09/2013 BIO 101 Lab Report Biological Molecules Introduction: In this experiment‚ simple chemical tests will be performed to identify the presence of various types of biological molecules. These tests take advantage of the fact that different types of molecules have different functional groups and‚ therefor‚ different chemical properties. Thus‚ they will react to test reagents (also called indicators) differently. Materials: Biuret‚ Sudan III‚ Iodine‚ Benedict‚ water

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more
