Safety glasses must also be worn throughout the lab to protect the eyes from chemicals. Potential injury may arise from razor blades and cork borers. Lab coats must be fully fastened to protect clothes from staining. 2. Chemical Hazards The solvents (acetone and methanol) should not be inhaled as it can cause damage to mucous membranes. They can also

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic
