Temp of hot water and metal 100.3 degrees C 100.3 degrees C 100.3 degrees C Final temp in the calorimeter 27.5 degrees C 32.2 degrees C 28.0 degrees C Calculations: Show your work and write a short explanation with each calculation. Part I: 1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. The water has absorbed

used to heat a strip of copper foil in the Bunsen burner. The copper was allowed time to cool and the spatula was used to scrape its surface. Also a strip of Magnesium was heated in the bunsen burner and when it combusted it was held over the ceramic plate. In part 2 of the lab 3 scoops of hydrogen carbonate were heated in a test tube and a lit wooden splint was put in the opening of the test tube. Also in part 2 of the lab the same steps were repeated with copper sulfate. In part 3 of the lab

the experiment is to analyze alum‚ AlK( SO4 )2 . 12 H2 O‚ by three techniques in order to verify its identity. The following properties will be determined namely‚ melting point‚ mole ratio of hydrated water to anhydrous alum‚ and percent of sulfate ion contained in the compound. Each of these properties will be compared to the literature or established values for alum. In this experiment‚ the first step ( Part 1 ) is to find the melting point of the compound and compare it to the published

The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic 20 at a wavelength

Title: Double Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is
