Slope Essay For years Mathematicians have studied and found various mathematical equations. One thing they’ve came across is numerous equations for slope. You maybe asking‚ what is slope? Slope is rise over run.To find slope (m=slope) on a graph‚ you draw and label your x (horizontal) and y (vertical) axis on a xy-coordinate plane. When you draw your two lines they should meet at right angles at a point zero. The axis is divided into four quadrants. Then you find any two points ( (0‚0) and (2‚1)

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

arithmetic circuit capable of performing both addition and subtraction on any two 4-bit binary numbers. The circuit has a Mode switch that allows you to choose between adding (M=0) and subtracting (M=1). To understand why this circuit works‚ let’s review binary addition and binary subtraction. We use 4-bit numbers in the examples because the main interactive circuit is a 4-bit adder–subtractor. Binary addition is certainly easier than decimal addition. You just add 0s and 1s. For example to add the

CHAPTER 1 Introduction Background of the Study Like many other hygiene convenience‚ shoe polish or can also be called boot polish is usually a wax ‚ cream or paste used by people to shine‚ water proof and restore the appearance of leather shoes. This extends the footwear’s life. This is made up of many kinds of chemicals and because of this; it can cause irritations‚ allergies to us. In our generation‚ shoe polish is used every day and companies produce a lot of it to meet the demands of

chose this Psalms 23 for it is a common Psalm for many Christians to be accustomed to. This poem was written by King David‚ one of the most famous kings that ever reigned in Israel. He guided his people through hard times‚ was victorious in time of war‚ and was known as being close to God. The speaker suggests a tone of comfort and sufficiency with the incorporation of using the conceit of the Lord and a protective and providing shepard. In verses 1 and 2‚ the Lord is depicted to provide physical

one of two very similar pentose rings. Ribonucleic acids contain the sugar ribose. Deoxyribonucleic acids contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions. The Nitrogen-Containing Bases There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings

Separating a Mixture of Compounds Exp. No. 2 name Chemistry 145 February 2‚ 2014 I. Purpose The purpose of this experiment was to separate this mixture into components‚ determine the mass and percentage of each component. In addition to test the accuracy of an alternative method of subtraction to find the mass of the sodium chloride directly. Start with a mixture of sand (SiO2)‚ sodium chloride (NaCl)‚ and ammonium chloride (NH4Cl)‚ and use these separation processes: sublimation filtration

Trans Women: A Population of Unrecognized Beauty For the first time in this woman’s life‚ she was coming face to face with a transgender woman. Her first inclination was to see the appearance of an amplified woman‚ with frilly clothing‚ glittery shoes‚ makeup galore‚ and long‚ beautiful hair. A walking Barbie doll‚ with a twist. To her dismay‚ she was entirely wrong‚ misguided by society and the media. It is not uncommon to witness uneducated individuals be completely led astray‚ due to their reliance
