Dalton and the periodic table

-
John Dalton was an English chemist, physicist and meteorologist. He was best known for introducing the atomic theory into chemistry, and his research on colour blindness, which is sometimes referred to as daltonism in his honour.
John Dalton released his first periodic table in 1803, when he released his atomic theory and his work on gas laws. His first periodic table only had 5 elements; Hydrogen, oxygen, nitrogen, carbon and sulfur. Dalton attempted to create à system to symbolise the elements, but it didn’t work, because it was replaced by à system of only letters, proposed by à swedish Jons Berzelius. This was done shortly after Dalton released the second volume of his periodic table, in 1808, which included new elements, and even compounds, but this version did not come out until 1827 and contained an even longer list of elements.
Dalton’s First list of elements, published in 1803 with other work, contained only five elements, a far cry from the 100+ that we have today.

When the second volume of his work came out in 1827, the list of elements had grown to 36.  His symbols may look strange since they were not easy to remember and have not been used since the work was published.

Everyday application of Hess's Law

  Everyday application of Hess's Law Burning calories, consuming food, driving home, we all should be familiar with these actions because we do them everyday, but what some of us don't realise is that all these actions related one fundamental law of conservation of energy, Hess's Law.   Hess's Law states that: regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. [1]   We will further discover how our indrustries, human body and drug production are related to this law and to better understand the science behind it. Industries Today, all our mass and low cost production depends on factories and industries and all these industries require huge amount of energy.   To keep everything the most efficient possible, these industries has to determine the method that is the most effective to produce a product based on the energy needed or released.   For example:  Car companies...

Recycling: Yay or Nay? A question that often is asked whenever the topic of recycling is at hand, is about how effective recycling processes are. After all, couldn’t the process just add on to existing production costs? Well, put simply, No. A common misconception is that recycling uses up more energy than making something new. In reality, recycling saves a large amounts of quantities of energy. For example, recycling aluminium cans can save up to 95% of the energy that would be required to make new ones from the raw materials - recycling a single glass bottle saves enough energy to power a 100 watt light bulb for hours.² In effect, the reasoning as to why recycling happens to be energy efficient in almost all cases is due to the fact that recycled materials call for much less processing in order to once again serve as useful materials. According to the American Geosciences Institute, two such processes which demonstrate this effect are that of glass and aluminium manufacturi...

Environmental Impact of Industrialization                                                                                                                                                               The onset of the Industrial Revolution in the mid 1700’s and early 1800’s brought upon new methods of manufacturing products in Western society. These new technological advancements included factories and machinery, which ran mostly on the energy produced from burning coal and natural gases. These factories were used to mass produce products that proved useful for people during these...
