ASSIGNMENT in DOMESTIC TOURISM and GEOGRAPHY *Rehabilitation of EDSA* *Reclamation of Manila Bay* Submitted by: NAEG‚ Nelian N. III-CTM Submitted to: Prof. Arnold Germina Reaction Paper Rehabilitation of EDSA: The rehabilitation of EDSA is one of the nicest ideas to ease the traffic in Metro Manila especially it is a major highway and almost everybody use it. In contrast to that‚ Pres. Aquino is right to suspend it and make further study about it. Surely‚ it will take time to

Worksheet - Acids‚ Bases and Salts 1. I am pure water. When heated my pH (increases‚ decreases)‚ because more of my water molecules dissociate. 2. I am a 0.020 M solution of weak acid‚ HA. If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

MEMORANDUM From: To: Subject: Calcium Chloride Best Purchase for Deicing Enclosures: (1) Data Record (2) Data Treatment (3) Environment Impact Research After hours of vigorous examination‚ we have come to the conclusion that calcium chloride (CaCl2) would be the best deicer to use on a naval base over sodium chloride (NaCl) and ethylene glycol (C2H6O2). In order to melt ice‚ deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has

Stoichiometry of a Precipitation Reaction Purpose: The purpose of this lab is to calculate the theoretical‚ actual‚ and percent yield of the product from a precipitation reaction. Also‚ to learn concepts of solubility and the formation of a precipitate. Procedure: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ Add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt

The reactivity series is the known series of how metals should react. It places Calcium as the most reactive (of the metals being tested in this experiment)‚ followed by Magnesium‚ Aluminium‚ Zinc‚ Iron‚ Tin and finally‚ as the least reactive (of the metals being tested in this experiment)‚ Copper. However‚ the results this experiment produced did not follow this trend. If the metal that produces the most hydrogen gas is considered the most reactive‚ in this experiment magnesium was most reactive
