How to Live a Healthy Lifestyle Want to get out of your potato lifestyle? All you have to do is follow a few simple steps and you’re on your way! Firstly‚ Healthy food is essential; you can say that if you eat healthily‚ you are healthy. If you’re just starting to have a healthy lifestyle‚ you probably don’t know healthy food. Eating healthily does not mean eating expensive foods. Basically‚ you should aim a diet that is low in salt‚ fat and prevent unprocessed foods. Ur diet should

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few.

economic‚ and cultural forces that come together and mutually constitute one another in distinctive and dynamic ways” (Sanchez‚ 2006‚ pg. 35). There are many factors which play into our identities and which work together to construct our identities‚ from a personal and societal standpoint. Several factors which contribute to our identities include: position‚ positionality‚ identity‚ and identification. In order to better understand these concepts‚ we will examine each of these constructs through definition

asserts that our lives are controlled by the society in which we live in and hence‚ there is no real free will at all. I hold a moderate view points between two extremes; I believe that we are always presented with choices‚ but these choices are limited. Those who assert that choice is just an illusion believe that humans are just programmed robots which works according to algorithm presrcibed in the chip.They believe that we are controlled by the society. Society determines how we think and what

Chemistry Changes Everything: ¹ᶟ¹I - Iodine¹ᶟ¹ An isotope is two or more forms of an element where the nuclei of the element has more neutrons than protons and normally each element only has one stable isotope of the element. Changing the neutrons in the atom also changes the atomic mass but not chemical properties. Radioisotopes are radioactive versions of an isotope where the atom or element has an unstable nuclei therefore emitting radiation. An unstable nuclei is created when there is either

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

Chemistry Review (mid-term) 1. Use the equation for atomic mass to answer the following questions. (http://johnheilchem10.escuelacampoalegre.wikispaces.net/file/view/average+atomic+mass+calculations+-+3.pdf) 1. Argon has three naturally occurring isotopes: argon-36‚ argon-38‚ and argon-40. Based on argon’sreported atomic mass‚ which isotope do you think is the most abundant in nature? Explain. 2. Copper is made of two isotopes. Copper-63 is 69.17% abundant and it has a mass of 62.9296 amu.
