put on black paper and left outside in the sun‚ the water would evaporate but the salt crystals would stay. The salt would not evaporate because it is a solid. Knowing this I formed a hypothesis‚ being‚ if salty water was poured on black paper and left out in the sun‚ the water would evaporate leaving behind the salt crystals‚ causing the part that the salty water was poured on to turn white. METHODS Materials: Salt Potting Soil coffee filter plastic cups black construction paper

have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy to the surroundings. Endothermic reactions take in energy from the surroundings.

hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce an acid-base molecule. A salt molecule that is not bound to any water molecules is an anhydrate‚ and a salt molecule that is bound to water molecules is a hydrated salt. In a hydrated salt‚ the water molecules are transforming into the crystalline structure of the salt Nowadays

de Uyuni Salar de Uyuni is the world’s largest salt flat located in Bolivia. It is over twelve thousand square kilometers in area‚ which makes it the largest salt flat in the world. It also has the distinction of being the highest salt flats in the world at three thousand seven hundred meters above sea level. From a distance the salt flats look like a huge white sea. When there is rain then something magical happens. The salt flats become a mirror of the sky. The origins

by promoting the idea of peace. The first talks about arms limitations tried to reduce tensions between the United States and the USSR. Although these talks did not seem to be effective at first (SALT I) they brought up an idea. Later on when the SALT II was introduced which was more effective. The SALT II agreement really strengthened ties between the USSR and the United States. This agreement reduced the number of nuclear weapons of each side because they had enough to destroy the world multiple

Abstract What is the effect of salt on the boiling temperature of water? Many people know the boiling temperature of water is 100 degrees. What if the boiling temperature can be increased by adding salt well it can. This experiment was a success. My hypothesis tested true my hypothesis states that the salt will increase the boiling temperature of water because different elements have different effects on each other. So I think the salt will increase the boiling temperature of water. The temperature

is often encountered as the heptahydrate‚ MgSO4·7H2O‚ commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water from the air) and is therefore difficult to weigh accurately‚ the hydrate is often preferred when preparing solutions‚ for example in medical preparations. Epsom salt has been traditionally used as a component of bath salts. Procedure: 1.to the 21.08 g of the magnesium carbonate in the 250ml beaker
