Industrial Chemical Processes Essay Tan Hung Kai Grade 11 In our present world‚ there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists

Weathering Weathering is the breaking down of Earth’s rocks‚ soil and minerals through direct contact with the planet’s atmosphere. Weathering occurs in situ or “with no movement” and thus should not be confused with erosion‚ which involves the movement of rock and minerals by agents such as water‚ ice‚ wind and gravity. In addition‚ weathering is the effect of atmospheric exposure to man-made structures and materials. Two important classification of weathering processes exist – physical and

SLFC PROJECT Chemical origin of Life and Life on other Planets Drishta Gopala‚ Sarthak Malhotra‚ Srividya‚ Suprigya Dipangi Theories for Chemical Evolution Of Life On Earth Introduction According to a mechanistic‚ naturalistic view of the universe‚ and thus of origins‚ the whole of reality is evolution — a single process of self-transformation. Everything in the universe‚ according to this view‚ has evolved from a primordial chaotic or random state of matter. This evolutionary

Limestone is a grey organic sedimentary rock made of calcium carbonate. A lime stone pavement is a large flat area of bare limestone from which soil cover has been removed over a long a period of time the acidic rainwater passes through soil it picks up humic acid from the rotting vegetation in the soil and becomes more acidicis. Rainwater picks up carbon dioxide as it passes through the atmosphere. As it passes through soil‚ the water picks up more carbon dioxide from organic debris. The water and

matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The higher the temperature‚ the faster the speed of the particles. The Biosphere‚ Lithosphere‚ Hydrosphere and Atmosphere

Internal processes which have been involved in the formation of boxwork weathered rocks. The major internal processes for my surface feature are: 1. The rock cycle and the formation of greywacke. 2. The uplift that brought the rocks from under the ocean up to the shore level. The rock cycle The rock cycle refers to the diverse set of natural processes that lead to the formation and transformation of igneous‚ sedimentary‚ and metamorphic rocks. The rock cycle shows that each type of rock can

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Shelby Brown 8/28/10 Physical and chemical changes lab essay Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing
