Empirical Formula Lab Class: Chemistry 1405 Fall 2013 Aim: The aim of this Lab Exercise is to use the mass of a chemical and use that mass to find the amount of moles of the final product you can get using the empirical formula. Introduction: The empirical formula of a compound is the simplest whole-number ratio of the elements in the compound‚ which as you will discover‚ is a ratio of the moles of those elements. “Empirical” also means “experimentally determined”. In this experiment

Functional Significant In William Faulkner’s “Barn Burning” certain objects function symbolically. One object is blood. The blood symbolizes the unity of the family. Loyalty and family ties are symbolic in the blood as well. Fire is also an important symbol in "Barn Burning‚” fire is in almost every section of the story but the fire that counts is the fire Abner builds the night the family camps out before arriving at the de Spain mansion. Another symbol is the wagon on moving day and spring.

Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

prevent buckling if the temperature range is -30Cº to +50Cº? I know I use the formula: L = LoT L = ? (Change in length of the slabs. We are solving for this.) = 12e-6 (Coefficient of expansion. I looked it up on page 388.) Lo = 14 m (Initial length of slabs.) T = 30 Cº (50Cº - 20Cº) (Change in temperaure. You only care about the hottest number since you are dealing with expansion.) I then had the formula: L = e14 m 30Cº L = .00504 m L = .50 cm The space between

Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

Fluid intelligence reflects information processing capabilities‚ reasoning‚ and memory. It is used to evolve the ability to think clearly. For instance‚ a person who is asked to arrange a series of letters according to some rule or to memorize a set of numbers uses fluid intelligence. Although it is defined as the inmate and learning caoacity of all individuals. To my knowledge fluid intelligence is used in so many ways‚ throughout the country. It normally affect’s children during childhood and
