1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

Its name of origin was from Borax and Carbon. Its melting point is at 2089°C and its boiling point is at 2550°C Boron was discovered by an American and two French chemists. When and how it was discovered It was discovered by Sir Humphry Davy‚ J.L Gay-Lassac and Louis Jacques Thérnard in June 1808. It wasn’t recognized as an element until Sir Humphry Davy did its first isolation in July 1808. At first Sir Humphry Davy tried to create Boron by electrolysis of Borax‚ but in the end he decided to

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

insecticides. Boron is essential to life. Small amounts of boron compounds play a strengthening role in the cell walls of all plants‚ making boron necessary in soils. The name boron originates from the Arabic word ’ buraq’ or borax. Boron compounds were known thousands of years ago. Borax glazes were used in China from AD300‚ and some even reached the West‚ where the Persian scientist Jābir ibn Hayyān seems to mention it in AD700. Marco Polo brought some glazes back to Italy in the 13th century. In 1777

that looked so amazing and beautiful behind the desert mountains. Later we came back to the hotel to sleep. The next morning we went to see the Borax Museum. It is the oldest house in Death Valley. Borax was found in the valley‚ which was a white crystalline. Outside of the Museum‚ we saw a 60 ton oil burning Locomotive. Inside we saw minerals from the Borax mining era. The next day we planned a camping trip at the Emigrant campground. First we went hiking along the Emigrant trails‚ then we went swimming

Experiment # 4a Title: Determination of the Hardness of Water from a Waterfall Aim: To determine the molarity of EDTA and to determine the hardness of water by measuring the concentrations of calcium and magnesium in a water sample by titration. Abstract: The aim of this experiment was to determine the molarity of a sample of EDTA and then to use this sample to determine the hardness of a sample of water. This was done using a titrimetric method. This was standardized using calcium chloride.
