Salt

contains a low concentration of dissolved salts, and a concentrate or brine one that contains the remaining salts (Department of Environment Australia, 2006). One of these methods is the reverse osmosis, in which pressure is used to pass water through a selectively permeable membrane, leaving salt behind. Also, there is the thermal method which is the oldest and consists in boiling water and then collecting the steam generated, separating it from the salts. Another desalination method is the…

video Hands-On Science with Squishy Circuits it talks about how easy it is to make electricity with things you probably have in your kitchen. Annmarie explains how play dough made out of salt conducts electricity. Using sugar play dough, salt play dough, and LED lights she demonstrates how it makes electricity. The salt…

Ice transforms at a point of degrees. This degree would be 32 degrees Fahrenheit or 0 degrees Celsius. It must be at this degree or lower to transform into ice. If it is higher than the freezing point of water, then it will be a form of water or ice melting into water. The different molecules, or also called the things that make up the ice or water, are more dense in cold water. They become dense and come to each other which makes them tight into an ice cube. When the ice gets warm, it moves the…

independence leader Mahatma Gandhi set out to fight against the Salt Acts that British had imposed on India. The Salt Acts required Indian citizens to pay the British for salt, which was a key ingredient in their diets, as well as an additional tax on the mineral. Gandhi saw disobeying the Salt Acts as a way to nonviolently break the law in hopes of gaining independence from Britain. He and his followers marched to the coast and made salt from the saltwater, openly breaking British law. Soon,…

Klaproth discovered the element in the mineral pitchblende, which at the time was thought to be a zinc and iron ore. The mineral was dissolved in nitric acid, and then potassium salt was added to the remaining yellow precipitate. Klaproth concluded that he had discovered a new element when the reaction between the salts and precipitate didn't follow any reactions of known elements. He claimed it to be a new element, but his discovery turned out to be uranium oxide and not pure uranium as he had…

colors, a firework makes will depend on what color-producing chemicals are in the firework. These chemicals are various material salts that burn up when the firework runs off, and using up the metals is why the colors is. Different metals produce different types of colors that are specific by nature. On this science activity, you'll get to melt away some metallic salts at home to research what colors they make. Then, at another fireworks show, you can win over relatives and buddies with your…

bake at 325 degrees for 10 minutes (approximately). Cool down the liners on the rack. H4: Chocolate Cupcakes Again, preheat the oven to 325 degrees. In a medium bowl, sift together all the dry ingredients like flour, baking soda, cocoa powder, salt, and sugar, and set aside. Mix together coffee, oil, water, and vanilla. In an electric mixer, add the sifted dry mixture to the bowl, and then add the wet ingredient mixture. Mix the both on medium speed until combined. Ensure there are no lumps…

because no system is completely just, it takes people sticking to their morals for change to be made. Peacefully resistance is an effective way of getting the message across. One famous example of civil disobedience in history is Mohandas Gandhi’s salt march. In the 1930’s Britain held rule…

on proteins. Therefore, protein is an essential part of healthy diet, and integral to development of the body. The purpose of performing this lab is to analyzing the activity of TEM-1 B-lactamase and how it reacts with high temperatures, chaotropic salts, detergents and pH values. INTRODUCTION: Primary protein structure is sequence of chain of amino acids. Secondary protein structure is a regularly occurring structure and is mainly formed when a sequence of amino acids are linked between by…
