1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

chloride and ammonia can be used to explain it. In aqueous solution‚ hydrogen which is an acid reacts with ammonia‚ a base to form a solution of the salt: ammonium chloride. According to Arrhenius the reaction occurs between the H+ ions formed due to the ionisation of the HCl when it dissolved in water. The OH- ion is also formed when ammonia dissolves in water. NH3 + H2O NH4 + OH- HCl + H2O Cl- + H2O- However‚ the reaction between ammonia and hydrogen

TT #4: Add .1 M AgNO3 solution by drops until a change occurs Part 3: Prepare a dilute ammonia solution (NH3 + H2O NH4+ + OH-) by adding 4 drops of ammonia to 100 ml of water. Add 3 drops of phenolphthalein (detects OH-). Pour 5 ml of the solution into each of three test tubes and follow the below procedure. TT#1: Add several small

center for cross-disciplinary research and gave his country the knowledge of ammonia and other significant fertilizers. He left Germany in 1933 after their loss in WW1‚ and passed away in Switzerland in 1935. The Haber Process combines nitrogen from the air with hydrogen from natural gasses like methane into ammonia. This process is a reaction that ’s reversible and the production of ammonia is exothermic.

nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more
