economically savvy for whoever is supplying the salt for these roads is essential when testing for deicing quality. There has been a lot of work done previously to find the most efficient deicer. We have been using salt to control snow and ice on roadways since 1930. However‚ we are now looking into the environmental effects of salts as deicers along with other potentially harmful effects. One current study is looking into the corrosive effects of salts on our vehicles. Experimental Our experiments

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

percentage by mass of water in Epson salt? DISCUSSION- When a crystal forms from water solutions‚ it takes a certain amount of water as part of the crystalline structures. The water is not covalently bonded to the host molecule or ion. Water is taken up in definite proportion in relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization

Box Performed: August 29‚ 2013 Submitted: September 5‚ 2013 Introduction The solubility depends on the properties of a solvent that will allow interaction with a solute more strongly than do solvent particles together. Water is the universal solvent. Water‚ certainly dissolves many types of substances and in greater amounts than any other solvent. The salt is a compound consisting of various minerals‚ and is one of the most abundant

SUGAR‚ SALT‚ FAT Our world‚ as a whole‚ is facing great challenges that affect our current and long-term health. We are stuck on the availability of processed food and need to break this vicious cycle that we are in. We need to take responsibility for ourselves and stop blaming it on consumerism. The big food companies have made it almost impossible to cut them out because health food is more expensive than what they offer. They have hooked us not only because of its
