...profoundly influenced the course of human civilization. Science has provided us remarkable insights into the world we live in. The scientific revolutions of the 20th century have led to many technologies, which promise to herald wholly new eras in many fields, As we stand today at the beginning of a new century, we have to ensure fullest use of these developments for the well being of our people. Science and technology have been an integral part of Indian civilisation and culture over the past several millennia. Few are aware that India was the fountainhead of important foundational scientific developments and approaches. These cover many great scientific discoveries and technological achievements in Mathematics, Astronomy, Architecture, Chemistry, Metallurgy, Medicine, Natural Philosophy and other areas. A great deal of this traveled outwards from India. Equally, India also assimilated scientific ideas and techniques from elsewhere, with open-mindedness and a rational attitude, characteristic of a scientific ethos. India's traditions have been founded on the principles of universal harmony, respect for all creations and an integrated holistic approach. This background is likely to provide valuable insights for future scientific advances. During the century prior to independence, there was an awakening of modem science in India through the efforts of a number of outstanding scientists. They were responsible for great scientific advances of the highest international......

Leads to values all higher or lower than actual value. High precision, low accuracy. Random Error → uncertainty in measurement devices. Leads to random variation in values. Always occurs and can generally not be improved. Precise measurements have low random error. Accurate measurements have low systematic error and generally low random error. Uncertainties: Graduated/Analog Device → ±1/2 of the smallest increment on the device. Digital Device → ±1 on the last digit the device records (it estimates for you.) Exact Values → No uncertainty. For all uncertainties the recorded value MUST be to the same decimal place as the uncertainty. Change your final answer's significant digits if necessary. Uncertainties should be rounded to ONE digit. Propagation of Uncertainties: Addition and Subtraction → Add uncertainties. Multiplication and Division → Calculate Relative Uncertainty by dividing...

...Chemistry 1.  5 points of the particle theory: * 1. All matter is made up of tiny particle with empty spaces between them * 2. Different substances are made up of different particles * 3. Particle are always in constant random motion * 4. Particles of a substance move faster as the temperature increases * 5. Particles attract each other 2. Changing state from solid to liquid to gas: * form a solid when the forces are strong enough to form a rigid shape * they gain energy when heated and begin to move faster, when they can no longer hold each other, this forms the liquid state * if they are continued to be heated the particles literally fly apart 3. The difference between pure substances and mixtures: * pure substance: contains only one type of particle * element: a pure substance that can not be broken down into a simpler chemical substance by any physical or chemical means * compound: a pure substance composed of 2 or more different elements that are chemically joined * mixture: contains 2 or more types of particles * mechanical mixture: a mixture in which you can distinguish between different types of matter * solution: a uniform mixture of 2 or more substances 4. Difference between quantitative and qualitative properties: * quantitative property: a property of a substance that is measured and has a numerical value, such as temperature, heat and mass * qualitative property: a property of a......

...should be a universal table for grouping elements together. As stated earlier Dmitri Mendeleev is considering the father of the periodic table of elements. Although he did develop what is essentially the foundation of the table we use today, it was actually Glenn Seaborg who finished his work and made the table that everyone uses today. Seaborg and his colleagues discovered the final elements on the table and rounded it out to its current state. Works Cited 1. “The Periodic Table." The Periodic Table.

...Insert your name Course Professor’s name Date due The Chemistry and Applications of Carbon Allotropes in Industry Introduction Carbon has the ability to create many allotropes because of its valence. This means that carbon has a high rate of combining power with other different atoms when it is in the process of forming chemical compounds or molecules. The most common allotropes are Diamond and Graphite. The different allotropes of carbon tend to shows different properties and have a different application in different fields. Diamond is a common allotrope of carbon that exhibits hardness and has a high ability to disperse light. Diamond is the hardest discovered mineral and industries find it useful in cutting and drilling of other elements. It is also used to manufacture jewelry. Graphite is another common allotrope of carbon. Graphite is formed in a single layer by graphene that consists of carbon atoms and it is arranged in a single plane. Graphite is a good electric conductor. Graphite is known as the most stable form of carbon under the rating of standard conditions. This paper will describe the chemical and physical compounds and their industrial application in different fields. Discussion Allotropy refers to a property of a particular chemical element that exists in more than one different form when it is found in nature. There are different forms of carbon that exists and this paper will discuss the common allotropes and their application in different fields.......

... | |Density (g/cm3) |2.8 | Generally the experiment relies on the accuracy of the measurements in comparison with its known or theoretical density. There were minor errors due to some inconsistencies specifically those of which were human errors in the measuring and the inherent limit of the instruments used. Generally speaking, the experiment was a great success due to its nearly accurate values in accordance with theoretical or known densities. REFERENCES (1) Figueroa, L. and Samonte.J.

...The chemistry of perming & rebonding Some of us have naturally curly hair but want it straightened; others have it naturally straight but want it curly. But whatever the style you like to wear, there's chemistry involved in it! The structure of hair Hair is made mostly of a protein called keratin, which is also present in nails. In hair, keratin molecules are arranged in straight bundles. These bundles are held together by disulphide bonds (-S-S-), which give strength to the hair. Disulphide bonds are made by the amino acid called cysteine. The cysteine of one keratin molecule forms a disulphide bond with the cysteine of the neighbouring keratin molecule. The more disulphide bonds there are in a strand of hair, the straighter it is. Ammonium thioglycolate: the perm salt Ammonium thioglycolate (HSCH2CO2NH4) is a compound that can break disulphide bonds. This is because it contains a thiol group (-SH). The thiol group replaces one of the sulphur atoms in the disulphide bond, like this: Keratin-S-S-keratin + 2HS-CH2CO2NH4 --> -HO2CH2CS-SCH2CO2H + 2NH3 + 2HS-keratin When the disulphide bond is broken, the keratin bundles come apart, and hair is weakened. Ammonium thioglycolate is therefore used widely in beauty parlours when customers want their hair re-styled. However, if you use too much of it, or if the reaction is left for too long, you could end up going bald. So do not, ever, try it at home! If you have watched the film Legally Blonde, you'll have seen Reese Witherspoon......
