CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

To determine the successfulness of the experiment and the amount of product(s) recovered‚ IR spectroscopy‚ Gas Chromatography and percent yield calculations were used. Equations and Structures 6.

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

IB Chemistry Experiment 4 Composition of a Post-1983 Penny Lab Report Background: Through the use of percent composition one can easily find out how much of a certain element is in a compound or an item such as a post-1983 penny. The experiment will be using HCl a strong acid to dissolve all the zinc inside the outer copper shell. The reaction follows as such; Zn+2HCLZnCl2+H2‚ but there will be no reaction with copper. The portion that will be measured is the mass of copper left after all of

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 &

For this to happen‚ the molecules need to dissolve through a partially permeable. Osmosis is the diffusion of water as it goes from dilute to a more concentrated solution. Active transport is the movement of molecules from low concentration to high concentration against the concentration gradient. Energy is required for movement to occur. Water Balance- Salt concentration in blood depends on how much water is reabsorbed

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

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil
