Activity 1.7.2 Synthesis of Esters Purpose- the Purpose of this lab is to synthesize Esters by combining Carboxylic Acid and Alcohols. In this lab we will synthesize and then detect the odour of Esters formed. Materials- Materials that will be used in this lab are as follows:- Ethanol 7. Acetic Acid Eye Protection 11. Test tube rack Procedure- Prepare a hot-water by half filling a 500-mL beaker with water and heating it carefully on a hot plate until it comes to a gentle

Haber process is the process for converting nitrogen and hydrogen from natural gas into ammonia. Control & Click to follow link. The Haber Process PPT.ppt Questions to Answer Questions that should be answered by the content of your research project: 1. Describe the process you researched‚ including its uses in various industrial or health fields. I chose to research The Haber Process. It combines nitrogen from the air with hydrogen that comes from natural gas‚ into ammonia. The reaction is

into the ground‚ it meets with the limestone. Limestone is mostly made up of the mineral calcium carbonate (CaCO3)‚ which is not very soluble‚ so the rocks don’t dissolve very quickly. But‚ if you add an acid‚ you add hydrogen ions (H+)‚ which will react with the carbonate to form hydrogen carbonate (HCO3- ions)‚ which are extremely soluble in water‚ therefore the limestone will start to dissolve. In the USA‚ sinkholes tend to occur in Florida‚ Texas‚ Alabama‚ Missouri‚ Kentucky‚ Tennessee‚ and Pennsylvania

of water is its high heat capacity. Heat capacity is the degree which a substance changes temperature in response to a gain or loss of heat. This means that water is able to take in a lot of heat before changing its temperature. This is caused by hydrogen

the solvent via hydrogen bonding‚ electrostatic forces‚ ion dipole forces‚ dipole-dipole forces and London forces. All of these can help a polar solute dissolve in an aqueous solvent. Polar molecules can be involved in these interactions because they have a partial charge. This partial charge is brought upon by the differences in electronegativity between the atoms in the molecule. The difference in electronegativity created a dipole in the molecule. The partially positive hydrogen atoms in H2O molecules

Valuable Experience Gained During the Training Period The valuable experience that I gained during the training is when we are in the furnace of the boiler where the combustion takes place. The furnace is a internal parts of the boiler so we are taking the advantage to see what’s inside the boiler. We saw the generating tubes‚ bunker fuel injector‚ grates that we need to fix because of mis-alignment of the grates base. Grate is use for de ashing to avoid clogging up of the boiler. The second

John Dalton was an English chemist‚ physicist‚ and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness‚ and of course‚ his Atomic Theory. His theory gave us an idea about what the universe is really made up of‚ and he paved the way for many more important scientific discoveries after he died in 1844. His theory was simple: He stated that all matter is made of atoms. He based his theory on two laws: the law of conservation of mass and the law of constant composition

fine magnesium powder tends to burn rather more slowly than a strip of magnesium ribbon‚ for example. Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid. The reaction involves collision between magnesium atoms and hydrogen ions. How does surface area affect a chemical reaction? If one of the reactants is a solid‚ the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid

Abstract: Carbon-hydrogen insertion reactions involve the insertion of a carbene‚ a neutral carbon atom or molecule with two unpaired valence electrons‚ into an unactivated carbon-hydrogen bond. This reaction produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves the release of nitrogen gas. The carbon hydrogen bond is extremely
