enumerated powers‚ reserved powers‚ and concurrent power. Enumerated powers are only powers for the National government. Reserved powers are powers only for the state government. Concurrent powers are powers for both state and national Government. This separation of powers was due to the people making sure that no one had more authority than others. This took away some responsibilities but it also gave states the chance deal with their needs the way that they wanted. The Enumerated powers belonged only

Unit Project Documenting the Scientific Method Separating Mixtures Project Separating Mixtures: How can you separate salt water to make pure and drinkable fresh water? Design and build a device to separate a mixture of salt water into its components. For example‚ what device could you build to get the most drinkable water from salt water if you were on a stranded island in the middle of the ocean? Gather data on the amount of water collected and the purity of the water‚ which can

Separation exists between society and the penal system‚ and due to this‚ there is a grave lack of knowledge of what is happening in prisons and how we can improve the situation we currently have in regards to the prison system. There are major flaws within the penal system‚ and Angela Davis highlighted a main one in secrecy. We know based off of research that our prison population commonly consists of individuals who struggle academically (Petersilia‚ 2003‚ pg 32). Because of this lack of strong

6. Results and Discussion 6.1. Mix Design of Cold Recycled Bituminous Mixture Compaction characteristics of untreated bitumen mixes according to Modified Proctor Test is shown in Figure 6. When the RAP content increased‚ it resulted in reduction of MDD and the corresponding increase in OMC. The decreased MDD is obtained due to the weak bond between RAP and the virgin material and also due to less fine material that plugs the voids to produce denser mix. The corresponding increase in OMC is

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

Introduction Atoms‚ molecules‚ compounds and mixtures‚ although they may not seem it‚ are different. Atoms make up all of the above and elements. They are made an equal amount of protons and electrons. Molecules are made when two or more atoms connect chemically. Like molecules‚ compounds are made when two or more atoms connect chemically. Unlike molecules‚ the atoms need to be two or more different elements. Mixtures are made of two or more compounds or elements. Mixtures can look completely the same when

What is the particle theory? The particle theory says that that matter consists of many small particles with spaces in between. The particles are constantly moving‚ the higher it’s temperature‚ the faster they move. All the particles are attracted to each other. The particles move faster and move further apart when heated‚ and the reverse when cooled. Each substance has unique particles that are different from the particles of other substances. Particle theory helps to explain the behaviour of

Discussion: Continuous distillation‚ a form of distillation‚ is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams. A distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling (or evaporation) and condensation. A distillation produces at least two output fractions. These fractions include at least one volatile

Separation by difference in particle size: Sieving: - Is a way pf separating mixtures of solids‚ or solids and liquids with different sized particles - The mixture is poured through a sieve and the particles smaller than the sieve pass through while the larger particles are trapped by the sieve - The are commonly used for cooking - E.g. a mixture of rice and water is poured through a sieve to capture rice and remove the water Filtration - Is a technique commonly used for mixtures of solids and liquid

MIXTURES‚ SOLUTIONS‚ SUSPENSIONS AND COLLOIDS MIXTURES A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures. SOLUTIONS A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even
