ENERGY BALANCE Desulphurizer Here Sulphur in Naphtha is made to react with Hydrogen in presence of catalysts to give Hydrogen Sulphide. This reaction takes place at a temperature of 623 K H2 + S Hydrogen and Naphtha are assumed to be stored at 303 K Specific Heat capacity of naphtha is assumed to be 3.5235 kcal/kmol Specific Heat capacity of Hydrogen =(6.62+0.00081T) kcal/kmol K ∆H = ∑ ni ∫ C pi dT = 6.015915 x10 6 kcal hr i Hence heat required to raise their temperature from 303 K to

created precipitation). To further conclude the identity of the 2nd unknown substance a second step was done‚ which was a pH test through the use of the universal indicator (measures pH by containing various indicators that respond differently to Hydrogen ions). A controlled test was done to ensure the pH scale was correct‚ and once the two concentrations were placed into the diluted indicator (through water) a distinct purple was achieved. This points closely towards either Sodium or Potassium carbonate

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain by a single covalent bond are called straight chain hydrocarbons. 12. Branched chain hydrocarbons

Electrolysis of water Use a U-tube with electrodes at each end‚ connected to a battery. Fill the U-tube with water. Turning on the battery‚ observe the results at each electrode. Next‚ test for hydrogen and oxygen gas produced at each end of the tube. 5. Burning magnesium Place magnesium ribbon in a clean crucible (on a clay triangle above

lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in determination of unknown compound. The color‚ odor‚ melting point and boiling point determines the physical state and properties of a compound. It also determines its volatility
