Pigments were first extracted from tomato paste by a 50/50 mixture of acetone/hexanes; these miscible molecules act together as one organic solvent. Pigments choose the organic layer over the tomato paste with water‚ which allowed for their extraction. K2CO3 is an ionic base that was added to deprotonate the citric acid. The ionic product of the reaction in figure 3 now prefers the aqueous layer‚ which serves to wash the pigments of the acidic impurity. Saturated NaCl pulls any water into the

Kinetic Art Kinetic art: the art of motion. Kinetic art contains a/or several moving parts and depends on motion for its effect. The motion of the art work can be provided in virtually any way. It can be powered by natures elements; wind‚ wave power from water‚ or heat from a fire; It can also be powered mechanically through electricity‚ steam‚ clockwork using earths natural phenomena’s ‚ gravity‚ motors‚ or even through the observer such as cranking a handle‚ or giving a push.

The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

Acetone is an extremely popular solvent that is used in rubber‚ resin‚ plastics‚ lacquers‚ varnishes‚ and rubber cements. It is also used in the creation of fats‚ oils‚ and waxes where is a primary component. Acetone has many uses in modern technology including those that relate to the medical field and various domestic uses. It is a very important organic compound found in everyday life‚ but it is also a toxin and can be an extremely dangerous environmental pollutant. Acetone has many valuable

Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating

Background of the Study Familiar household uses of acetone are as the active ingredient in nail polish removers and as paint thinner. Acetone can also be used for medical and cosmetic uses‚ such as applying acetone with alcohol for acne treatments to peel dry skin. It can also remove residues from glass and porcelain and it can also remove super glue from the skin. Perhaps‚ acetone is very useful in our everyday lives. Acetone is also known to remove ball pen marks on fabrics and clothings

experiment is to see if we can recycle polystyrene using acetone. If this is possible‚ this can be used to help improve our environment since polystyrene itself is not biodegradable. Hypothesis: I hypothesis that polystyrene‚ mainly known as styrofoam‚ can be recycled using acetone. This cost efficient and easy method will not only motivate both individuals and industries to recycle but also improve the state of our environment. Materials: 100% acetone nail polish remover 3 small containers 4 Styrofoam

We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the
