AP Chemistry Kinetics Lab Abstract: The purpose of this lab is to learn how to write law expressions‚ determine orders by graphs‚ and calculate rate constants. By determining the number of drops of sodium hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st

Between Organic and Unorganic Food As we know‚ food is the most important thing in our lives. We can not live without food‚ it sounds redundant but that is the reality. Imagine if we do not eat any food in a day‚ we will get very not powere because we do not get the strength that is contained in food. We realized this important thing and now we have found that there are two types of food‚ organic and unorganic food. Many people still missunderstanding about the definition of organic and unorganic

Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter on the lab bench and a sample of sodium chloride (NaCl) on the balance. 2. Record the mass of the sodium chloride in the data table.

This experiment has been carried out to observe whether the hamster prefers organic or conventional foods better. Hammy was put into the place where there were two identical pieces of food‚ one organic‚ one conventional and it gets to choose either of them to eat. The reason hamster is used instead of the human is because it is unbiased‚ it judges the food from the smells unlike human that we have more complex thinking and tends to be considering about other things. Also‚ the human body is not good

sulfuric acid in order for it to be effective. The name of the ester formed is butyl ethanoate. This is because the ‘-anol’ part of the alcohol name becomes ‘-yl’ and the carboxylic acid part which has the name of ‘-ic acid’ will end with a ‘-ate’ 1-butanol + ethanoic acid butyl ethanoate + water.

Comparison between organic food and natural food Natural food also can be called as Natural product that produces with natural ingredients. All things considered‚ the naming of something as either "natural " or "non-natural" should imply that the item "does not contain included shading‚ counterfeit flavors or manufactured substances‚" however in all actuality‚ it’s anything but difficult to discover the these words on nourishments and beverages that are stacked with fake hues‚ flavors‚ additives

The study of urinary chemistry on stone forming minerals will provide a good indication of risk of stone formation. Urinary supersaturation with respect to stone-forming constituents is generally considered to be one of the causative factors in calculogenesis. Though supersaturation of stone forming salts in urine is essential‚ abundance of these salts by itself will not always result in stone formation. Various substances in the body have an effect on one or more of the stone forming processes (nucleation

Volatile Organic Compounds (VOCs) have become the greatest challenges to the preservation of the environment today. This group of chemicals is used in almost every sphere of life from industries‚ government institutions and domestically by both an ignorant and knowledgeable public. This paper aims to put to light examples of such compounds‚ look at the effect on the general populace and the environment and outline possible remedies to negative impacts. At the same time‚ it is important to look at

EFFECTS OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile
