This would be good because it is very likely that every group would get different results and have to explain more in their discussion about errors and if they think that their answer is accurate or not. Thus, the energy change is endothermic. [27][28][29] (Indeed, the word for ammonium chloride in several Asian languages derives from the Iranian phrase anosh adur (immortal fire), a reference to the underground fires. In Iran, Tajikistan, India, Pakistan and Arab countries it is called "Noshader" and is used to improve the crispness of snacks such as samosas and jalebi. In my experiment, the temperature of 3g of Ammonium Chloride-in 10ml, 50ml, 100ml- over the first two minutes instantly drops, however, it increases in temperature again in the next 3 minutes. Subsequently, 20 mL of the prepared isonormal N solutions were poured into the centrifuge bottles to give 0, 1000, 2000, 3000, and 4000 g of added N sample 1 . I have hypothesised that the temperature of the chemical reaction between water and Ammonium Chloride will heat up at a faster rate in 10ml of water compared to 50ml and to 100ml. The mixture was then heated up again and using steps 7 -11 the process was repeated two more times to get the most accurate results of the crystals forming with 4gms of solid Ammonium Chloride. The reason the temperature could have been wrong is because when I stirred the mixture, the heat from the bottom of the test tube would have mixed with the cool temperature at the top of the test tube, meaning that when you saw the first crystals appearing the temperature could have still been changing. The average of the 4 and 5 grams of ammonium chloride in comparison to graph 2 could be reliable but the percentage of error is too high for this to be acceptable meaning that there was an error in the consistency of the experiment. When ammonium chloride dissolves in water, the solution becomes colder. The maximum amount of a substance that any solvent can dissolve depends on the temperature of the solvent, e.g. A link to the app was sent to your phone. Is mixing ammonium chloride and water a chemical change? How to determine whether the enthalpy of solution is positive or negative by calorimetry? 1. When heated, calcium hydroxide and ammonium chloride react to produce ammonia gas, water vapor, and solid calcium chloride according to the chemical equation: CaOH + NH4Cl ==> NH3 + HO + CaCl Suppose 5.00 g of calcium hydroxide and 10.00 g of ammonium chloride are mixed in a test tube and heated until no more ammonia is given off.
