In chemistry, substances consist of large particles. As a result, the best way of expressing these particles is through a unit called a “mole." Therefore, a mole represents the amount of these particles in chemical substances such as chemical elements and molecules. For instance, a specific gram of a chemical element can contain many atoms. A mole is described as the quantity of a chemical substance with 6.02214076*10 23 discrete entities as the number of atoms present in 12 C, which weighs 12g. This number represents Avogadro's constant (N A ). Particles represented in a mole encompass molecules, polyatomic/monoatomic ions, atoms, electrons, etcetera.  The Avogadro's constant is considered "per mole" in chemistry and rounded off to 6.022*10 23 /mol. For this reason, one mole of a specific element comprises the same amount of atoms as represented in one mole of another element. However, a mole of distinctive elements contains different masses since specific atom...

  Picture 1: Before Application of Lumax 537.5 (SE ) As several farmers are searching for the best herbicides, there are various herbicides in the Kenyan market. The presence of a wide range of herbicides in the Kenyan market overwhelms farmers. As a result, they sometimes choose the wrong herbicides, which result in huge losses in their farms. Most farmers have inadequate knowledge of the types and specific applications of herbicides in Kenya. This article discusses the Lumax herbicide, its type, content, uses, how it works, mixing ratio, and its effectiveness. Picture 2: After Application of Lumax 537.5 (SE) What is Lumax 537.5 SE? Lumax is a selective herbicide . It is manufactured by Syngenta Company. In Kenya, it is packaged in 1L and 5 L. It is a broad-spectrum herbicide for both post- and pre-emergence. Contents and formulation The following are active ingredients in Lumax 537.5 SE: Terbuthylazine Mesotrione S-metolachlor 125g, 37.5g, and 375g of terbuthylazi...

Paper instructions: Choose a famous chemist (living or non-living) and write a two-page essay describing the life and work of the chemist. Your essay should include the following: Explain why you chose this chemist Provide a brief history of the chemist’s life (when they were born, their childhood, education, etc) What made this chemist famous? What was their impact on the field of chemistry? A bibliography (a reference list containing only Wikipedia is strongly discouraged) The essay should be 12 pt font and double spaced, and write in MLA writing style. Reason for choosing Antoine Lavoisier Antoine Lavoisier Antoine Lavoisier transformed chemistry to a large extent. Lavoisier named elements such as carbon, oxygen, and hydrogen. He also discovered the role of oxygen in respiration and combustion. He found out that water is a compound, which is made up of hydrogen and oxygen atoms. Lavoisier established that sulfur is an element, and revolutionized c...
