Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4 of the

:_________________ Date Submitted:__________________ Experiment # 2 Density INTRODUCTION: The density of a substance is physical property that requires measurements of mass and volume. The ratio of the mass per unit volume is density‚ d and is written as (D = m/v). Using the metric system‚ the ratio for solids and liquids is expressed in g/mL or g/cm. Matter expands and contracts according to temperature. For liquids and solids‚ the change in volume is very small‚ but for gases‚ a temperature

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze
