LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt‚ x. The salt is crystalline‚ deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt x with NaOH‚ or NH4OH the cation could be distinguished by observing the color changes or solubility while reacting salt x with H2SO4 or a mixture of copper

"The Hunger Artist‚" which is Kafka’s masterpiece‚ suggests that humans can never satisfy their desires. "The Hunger Artist‚" which is a story about a man who professionally fasts in a cage‚ is limited only 40 days of fasting by his manager‚ even though the artist believes he can last much longer. The Hunger Artist still remains unsatisfied even after his very pleased crowd leaves. The artist eventually hires himself out to the circus. However‚ the crowd only watches him because he is near the animals

Finding the Ratio of Moles of Reactants in a Chemical Reaction Purpose: The goal of the lab is to determine the mole ratio of two reactants in a chemical reaction (AgNO3 and K2CrO4). However‚ the formulas for the products are unknown. Introduction: When determining the molar ratio of a chemical equation‚ usually the formulas of the reactants and the products are known. With that information‚ it is particularly easy to determine the ratio. However‚ since the products and the formulas for

Title of Research: Finding the Value of One (1) Strategy: Its Effect on Pupil’s Speed and Accuracy to Add and Subtract Dissimilar Fractions. I. Introduction/Background of the Study Addition and subtraction of dissimilar fractions is one of the competencies that should be mastered by a pupil before he/she will graduate in the elementary. (PELC‚ BEC‚ 2002) However‚ this skill is one of the skills that is least mastered by pupils. It has been observed that Grade VI-pupils have difficulty in

Finding True Identity Women who immigrated to America during the 1950s and 1960s to escape the communist revolution struggled to transition from Chinese to American culture‚ while still establishing their own identity. The Joy Luck Club describes the relationships between recently immigrated Chinese mothers and their culturally confused daughters. Because the daughters of the novel are genetically Chinese and have been raised in Chinese households‚ they struggle to fully adjust in the modern American

Lumacad‚ Eugine A. English 3 (Technical Communication) Mendez‚ Charles Wayne M. I. Introduction Suspension bridges in their simplest form were originally made from rope and wood. Modern suspension bridges use a box section roadway supported by high tensile strength cables. In the early nineteenth century‚ suspension bridges used iron chains for cables. The high tensile cables used in most modern suspension bridges were introduced in the late nineteenth century. Today

Conclusion The research question that I asked myself before the experiment was “What is the osmotic potential of potato?” The answer I got after the experiment was that the osmotic potential of potato is very high because this experiment exactly showed what happened when there is Osmosis present and the following information will prove it. Our results greatly showed that there has been osmosis present. Osmosis is the diffusion of water through a partially permeable membrane from a region of lower
