In my experiment‚ I investigated the question “How does the amount of solute affect the time it takes for the solute to dissolve?” I thought about this question for a very long time and come up with a hypothesis for the investigation was “If the amount of solute increases‚ then the time for the solute to dissolve will increase. This is because the solute will become more concentrated and it won’t disolve into the solvent as fast. (Sadner‚ 2008)” Looking at the data I collected‚ I think that this

It is better to prevent waste than to treat or clean up waste after it has been created. Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible‚ synthetic methods should be conducted at ambient temperature and pressure. Chemist Vilas Pol came up with an environmentally green method that breaks down plastics and transforms them into a highly usable substance for society. Chemist Vilas Pol inserted plastic bags

Maria Reyes iLab‚ Week #4 CHARLES’ LAW Introduction The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases‚ so does volume. This also indicates that as temperature decreases‚ the volume decreases as well. Procedure 1) Select a 60 mL Syringe Sealed from the Gas Syringe item under the Equipment menu. Set the volume to 20 mL in the Initial

Heat Food Lab * Purpose: * Understand how to calculate calories per gram from burning food in the laboratory. * Understanding how to use the food nutrition label on the back of the package to calculate the calories per gram. * The calculated calories per gram in the laboratory are compared to the calories per gram that were calculated from the nutrition label. Then the % error and % yield are calculated and displayed in table and in a graph. * Students will be able

Introduction In thermo-fluid sciences‚ the measurement of temperature plays a key role. During this lab we tested two different types of thermocouples‚ a T-type and a J-type. Measuring with a thermocouple allows us to measure the temperature difference between two junctions. There are several laws that deal with the thermocouples and reading of temperatures. We use the first law of thermodynamics which states that there is a conservation of energy. Also the law of homogenous metals is in

Checkup: Linear Functions Answer the following questions using what you’ve learned from this lesson. Write your responses in the space provided‚ and turn the assignment in to your instructor. 1. What is the slope of the line in the graph below? Show your work. Answer: To find out the slope‚ you must first take two separate points on the graph‚ such as (-5‚-1) and (0‚1). Then‚ it’s a simple matter to use the equation [pic] to find the slope: [pic]=

Biodegradable Styrofoam Made from Milk and Clay Objectives - The researchers will intend to develop the Styrofoam-plastic out of mostly milk proteins and clay. The material is lightweight‚ sturdy and largely biodegradable. The researchers will make sure that the end result doesn’t smell like spoiled milk. - Casein—milk proteins—is already used in making paper coatings and has an excellent barrier properties. But it has its limited mechanical strength and is water resistant. To make it more resilient

Purpose and Intro The purpose of this lab is to determine the rate at which germinating peas respirate at varying temperatures and stages of germination. Cellular respiration is the set of metabolic reactions and processes that takes place in an organism’s cells in order to create ATP from sugar. It occurs in the mitochondria and comprises three stages: glycolysis
