For the unknown light source‚ it had almost every color‚ so it might have been be mercury because they have similar color beams and their color from the naked eye appeared as purple‚ which mercury‚ a light blue‚ is very close to in terms of it’s color on the spectrum. For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the

LabVIEW (Laboratory Virtual Instrument Engineering Workbench)‚ created by National Instruments is a graphical programming language that uses icons instead of lines of text to create applications. A LabVIEW program consists of one or more virtual instruments (VIs)‚ Virtual instruments are called such because their appearance and operation often imitate actual physical instruments. The objective of developing a virtual interface that acquires data from physical instrument (pH probe) used in the monitoring

Title Laboratory Techniques and Measurements Purpose The purpose of this experiment is to determine mass‚ length‚ temperature‚ volume‚ and density of objects and liquids using common measuring devices and algebraic formulas. The metric system‚ the most common set of measurements used in science‚ which includes meters‚ liters‚ Celsius‚ and grams will be used. Procedure The following items were used within the experiment: (1) Metric ruler with centimeter (cm) and millimeter (mm)‚ (1)

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on

THE RULES AND REGULATIONS The following safety rules must be observed while performing any of the scheduled laboratory experiments in one of the Chemistry Laboratories. Students who are found in violation of the safety rules will be given a warning for the first offense‚ will be dismissed from the lab room for the second offense‚ and will be withdrawn from the class (lab as well as lecture) for the third offense. If a violation is observed at a particular lab table (such as spilled liquid - water

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of
