manyfailing unions to come. In 1877‚ railroad workers in this union from across the country took part in anenormous strike that resulted in mass violence and very few reforms. Afterward‚ a editorial in The New York Times stated: “the strike is apparently hopeless‚ and must be regarded as nothing more that arash and spiteful demonstration of resentment by men too ignorant or too reckless to understand their own interests” (Doc B). A failure of this immense magnitude should have been enough to put it to

it’s expensive. The aim of this project is to create a new Smarties box size/design that uses a smaller amount of cardboard than the first model‚ but it needs to have the same volume as the original model. Q1. Use a piece of A4 paper to make a box with a length of 10cm and a width of 3cm. Then find the volume of the box and the total surface area of the paper used to make the box. T.S.A: 5 rectangles and 4 squares 5 x L x W + 4W = 5 x 10 x 3 + 4 x 9 = 186cm Volume: 5 rectangles and 4 squares

MCOPS‚ Manipal ANALYTICAL METHODS FOR RESIDUAL SOLVENTS INTRODUCTION: Organic solvents are routinely applied during synthesis of drug substances‚ excipients‚ or during drug product formulation. They are not desirable in the final product‚ mainly because of their toxicity‚ their influence on the quality of crystals of the drug substance and their odor or taste‚ which can be unpleasant for patients. To remove them‚ various manufacturing processes or techniques (usually under

A cylinder is a shape with a circular bottom at the both ends that kind of looks like a pringles potato chip bottle THE formula of finding the volume of a cylinder is base area times height of cylinder. The base area will be the area of the circle which is pi x radius x radius So you just take that answer and multiply it by the height of a cylinder. done math math math cylinder cylinder asdfghjk lkjhgh jhgf ghjxskdskdgc kdshfkhshfkshksskkkkjs wordlimit mine is

To begin this experiment we first had to collect a sample of salt‚ sand‚ and calcium carbonate that had been placed in a numbered vial. Then we numbered one of the 250 mL beakers “Beaker 1” and recorded its weight using the electronic pan balance. After weighing the beaker 3.5 to 4 grams of the mixture had to be added and the exact weight of the beaker and the mixture had to be recorded. Then 50 mL of distilled water had to be added and the mixture had to be stirred for one minute before being poured
