Acid rain is perhaps the most well-known and recognizable form of pollution that is affecting the world today. Acidity is measured using a pH scale with 7 being neutral. So anything below 7 is considered to be acidic. but as far as acid rain goes. the baseline for identifying acid rain is generally below the…

IntroductionIn this lab I observed the burning of a candle very closely. I found out that the candle needs oxygen to burn, that it produces carbon dioxide similar to the way that my body produces carbon dioxide, and that a candle produces water as a second waste product. I learned that if I hold an…

It was because of the lack of purity and crispness within Adams’ first hotplate that drove him to develop a better way in which he could capture the raw beauty of nature. By searching for ways to better nature and landscape photography, Adams construct the Zone System and Group f/64; which helped Influence the development…

The analyses of the mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques, we examined our solutions such as SiO2 (sand), NH4Cl (ammonium coloride), and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions, we made…

SOLAR ECLIPSE As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun. This can happen only at new moon, when the Sun and the Moon are in conjunction as seen from Earth. In a totaleclipse, the disk of…

“A carbon fiber is a long, thin strand of material about 0. 005-0. 010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for…

Determination of the Waters of Crystallisation/ Water of Hydration, In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these, as suggested by the use of the word hydrated in…

Industrial Minerals what it is all about? Is it really important to us? When I read the topic, my curiosities begin to start & ask questions in my mind. Industrial Minerals are geological materials which are mined for their commercial value, which are not fuel and are not sources of metals. They are used in…

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

General chemistry covers the composition of a solution, which consists of a solvent and a solute. The solvent is the primary component in the solution, while the solute is dissolved within it. Solubility indicates how much solute (in grams) can dissolve in 100 g of solvent until saturation occurs. Conversely, molar solubility measures the quantity…
