created a system of shared government through the Supremacy Clause‚ the Powers of Congress‚ and the Tenth Amendment. The federal system created by the Constitution was a reaction to the British government and defined the power of the national government. The founders wanted to avoid having one central source of power. In Article VI of the Constitution‚ the supremacy clause gives the national government to have jurisdiction over state government (Kernell et. al. 2014 pg 95). This allows for the national

Communist Party of the Philippines (CPP)‚ and the Muslim separatist movement of the Moro National Liberation Front (MNLF). One of his first actions was to arrest opposition politicians in Congress and the Constitutional Convention. Initial public reaction to martial law was mostly favourable except in Muslim areas of the south‚ where a separatist rebellion‚ led by the MNLF‚ broke out in 1973. Despite half-hearted attempts to negotiate a cease-fire‚ the rebellion continued to claim thousands of military

Aim: To investigate the difference between the melting point of dark and milk chocolate. Hypothesis: If both chocolate is heated then dark chocolate will melt faster because milk chocolate has more fats Variables (i) Independent: Two substances will be tested dark chocolate and milk chocolate. (ii) Dependent: The temperature at which each substance melts

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid.

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate

iBILIB REACTION PAPER (CHEMISTRY) The rock that was used in experiment #1 is not just an ordinary rock because it’s a calcium carbide and was known here in the Philippines as kalburo. When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas.

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

Examine the reactions against both dark and white backgrounds. If there is no reaction for that combination of solutions write NR (no reaction). Before beginning‚ set up a data table similar to the Data Table: Solubility Rules Table in the Lab Report Assistant section. CAUTION! Sodium hydroxide is caustic and can burn skin

Background: An ionic compound is formed when ions “transfer‚” or lose or gain electrons. The ions in an ionic compound are held together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate. A precipitate is solid that is formed from a chemical reaction. A cation is a positively charged ion and an anion is a negatively charged ion. Hypothesis: The anion and the cation
