Soda Ash Lab Report

Wool became scarce, silk hard to get and expensive, and rubber unavailable for civilian use. The lack of traditional materials led to increased research toward the production of synthetics.” (Batchelor) Regardless of the strict regulation of fabrics necessary for fashion, along with the scarcity of the materials overall, the United States continued to perform at what it excelled in: innovation. In 1935 the first synthetic fiber was produced, and it released a lot of the strain that was put purely on silk, cotton, and other fabrics.

Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with

Fundamentals of Fashion And Their Reflection In “The Next Black” Aaliya Gujral Unquestionably clothes are a prominent part of our lives. They help us express who we are and often represent our sex, occupation, age and social standing. Clothing has been used by humans for thousands of years, and comes in a variety of forms. It has evolved throughout the course of history to include more fabrics, patterns, styles and designs.

Throughout the history of humanity, various products made by man have evolved through the changing technological ways of society. However, not many people think of textiles as a product that has undergone many stages of advancements, not only in production of the product, but the designs of it as well. Even during the Elizabethan Era, textiles were seen as a vital product in the marketplace for not only economic reasons, but for cultural purposes. Every new era of a culture brings new ideas and historical events that affect all artistic products, especially textiles. Since the Elizabethan Era, textiles have been shaped by history, culture, and new fashion trends which cease to rapidly change in even today’s present day society.

Decomposition of Leaf Litter in Aquatic System Name: Aisha Ali Ahmed Al-Khan ID:90165 ----------------------------------------------------------------------------------------- Introduction Leaf litter is important for many organisms. It provides nesting materials, microhabitat for microorganism and provides protection. Bacteria, fungi and some invertebrates in the leaf litter benefit by feed on it and using them as shelters.

The material of the gown is fully made of cotton, with a washed out navy blue color. This dress is worn majority of the film by itself, however it is displayed with other costumes such as the tan coat, vest, and bright blue

The first thing you need to do when making your swaddling blanket is to pick out your colors and thread. Be creative as this is your own unique masterpiece for your child, and they are only young once. After you have your colors picked out, you will then need to pick your fabric. Baby fabric tends to be the most popular and practical, but the key is to make sure that it's comfortable

Imported from Europe aniline dyes was the first dying choice. Ancient Aztec clothing often colorful and loose fitting. Huipil, traditional garments worn by indigenous women of Central America and Central Mexico would have ribbons, lace and other intricate designs. These are just a few of Mexicans traditional clothing (Facts about Mexico no date).

In acidic aqueous solution, a buffer is formed by the dissociation of the acid: HA ⇄ H+ + A- Hence, when acid is added, the excess H+ reacts with the A- to form more HA, lowering the pH and minimising the effect of the addition of acid. When alkali is added, the OH- reacts with the dissociated H+ to form water, which reduces the effect of the alkali by restoring the pH to normal levels. Alka Seltzer acts as a buffer because the citrate ions in solution (C6H5O73-) are able to react with H+ when acid is added, to form citric acid, C6H8O7. This neutralises the acid, increasing the pH. The excess HCO3- ions also react with H+ to form CO2 and water, hence lowering the pH and reducing the acidity of the solution. The HCO3- ions also act as a buffer when alkali is added, because they react with OH- to create water and CO32- ions, increasing the pH and reducing the effect of the addiction of alkali.

INTRODUCTION Pigments are zilch but a naturally existing colored composite that absorbs light in the visible range of the electromagnetic spectrum. Most pigments are used in manufacturing and visual arts. These pigments could be employed to dye not only natural fibers like silk, cotton and wool, but also synthetic fibers like nylon and vinylon, and generally gave a good color tone. Synthetic inorganic chemical manufacturing rather than by grinding and washing clays or minerals taken directly from the earth. Several synthetic inorganic pigments are still used today, including iron blue, cobalt green dyed mainly with synthetic pigments.

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

The first synthetic dye, Mauveine, was accidentally discovered by William Henry Perkin in 1856 while he was looking for a cure for malaria. Different dyes are made of different dye molecules. Dyes have colour because they absorb light in the visible spectrum (400–700 nm), have at least one chromophore, have a conjugated system (a structure with alternating double and single bonds), and exhibit resonance

Woven, knitted, matted or bonded, they form fabrics that are needed to society. The issue we are dealing with is major, often us as people don’t pay attention wo what affect we have on our environment and the world we live in. we become selfish where money is involved. We often thing that when the word “natural” is a said we automatically think that there is no harm to the earth and that its all natural, however that’s not true.

Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.

As well, this study is also important because it could affect the manufacturing of the candles, in terms of amount of materials and dyes that should be added to the candles, especially from safety and environment perspectives. Evaluation: Limitation How This Limitation Affected Your Results Realistic Improvements The height of the candle used in the experiment was relatively small, which made the measuring process challenging.
