The internal combustion engine is a very inefficient way to power a car. Most of the energy of the fuel is wasted creating heat. This heat, if not removed, will quickly cause the engine to get so hot that the metal parts will melt. The cooling system is there to remove that excess heat. As…

Anders Celsius South Texas College Chem1411- General Chemistry I For Dr. Joe Studer Anders Celsius Although his name sounds like the conversant unit for temperature, he is also known for being a Swedish astronomer and a mathematician. His works contributed a lot to the scientific industry. From the beginning of his life, he always had…

Prelaboratory assignment Examples of questions related to the Dumas method: How many grams of ethanol would occupy 750 mL at 790.5 torr pressure at 100oC? (molar mass of ethanol is 46.0 g mol-1) Relavent equations: PV = nRT 1 atm = 101.3 kPa R = 0.8206 L atm mol-1 K-1 P = (750 torr)(1atm/760 torr)…

The intent of this lab was to: Determine the heat of neutralisation for the reaction of Na hydrated oxide ( NaOH ) and hydrochloric acid ( HCI). Requirement The heat of neutralisation ( ?Hneutzn ) is the heat transferred when 1 mol of an acerb reacts with 1 mol of a base. This heat is…

What is Cool There are many definition of cool. The meaning of the word depends on the user and the circumstance. There are many areas in life that the word cool can be applied in. Examples of the application of the word is “cool” air, or a teenager who wants to be cool in class….

The visible radiation from a glow stick will snuff out more rapidly at higher temperatures because temperature affects the rate of the chemical reaction. Question: Will a glow stick snuff out more rapidly while in a higher temperature? Purpose: To find if a freshness stick will decease out quicker in a cold temperature or a…

According to the kinetic molecular theory, gas particles are constantly in motion just like other forms of matter. However, their movement is distinct in that it is characterized by random translation. In solids, the particles primarily undergo vibrational motion. In liquids, they mainly vibrate and rotate, and also experience some translational motion. Gas particles move…

To analysis the proportion of an element in a certain substance, the experiment could be done by gravimetric analysis and volumetric analysis, and these two methods of analysing could be occupied on several different purpose of experiments as well. In a specific experimental condition, there will be one method that is the most suitable to…
