Economy - overviewzz Philippine GDP grew 7.6% in 2010‚ spurred by consumer demand‚ a rebound in exports and investments‚ and election-related spending‚ before cooling to 3.7% in 2011. The economy weathered the 2008-09 global recession better than its regional peers due to minimal exposure to troubled international securities‚ lower dependence on exports‚ relatively resilient domestic consumption‚ large remittances from four- to five-million overseas Filipino workers‚ and a growing business process

A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The

How sodium chloride concentration affects the germination‚ growth and development of Brassica rapa. Osumi‚ K.‚ Nihei‚ B.‚ Takanishi‚ K.‚ Nakamura‚ C.‚ Warehime‚ R. Period 2. 03/05/17 Introduction: To have a successful germination‚ the plant seed needs a sufficient amount of water and oxygen present. Other conditions include room temperature‚ and the amount of light intake. Hydration of a seed‚ is an essential step for seed germination (Martínez-Andújar‚ 2014). Plants tend to germinate better in

Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used to soften water‚ which makes it useful in soaps and laundry detergents. By chelating the metals in hard water‚ it lets these cleaners produce foam and work better without need for water softening devices. Citric acid is the active ingredient in some bathroom

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Bacon‚ Toast‚ Sodium Nitrate and Potassium Bromate For Breakfast Samuel Martino Have you ever looked at the ingredients on the side of a food package? There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

Lab Report Acids and Alkalis: Chemistry of Neutralization and Salt Formation Introduction: An acid is a group of chemicals. Acids are positively charged ions‚ they are liquid and are solutions of pure compounds in water. If you want to know if something is an acid‚ you can test it by using litmus paper. Acids will turn litmus paper red‚ whilst alkalis will turn it blue. Alkalis are negatively charged ions and are usually solid. Aim: To find out how much of different acids is needed to neutralize

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment the objectives were to try and predict the amount of product that was produced in the precipitation reaction of calcium carbonate by using stoichiometry. Then learn how to figure out the actual yield‚ theoretical yield and percent yield of the experiment. Experiment and Observation: The first step in the experiment was to weigh 1g of CaCl2 +2 H2O‚ then pour it into the 100mL
