The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity

In fermentation the pyruvate is converted into ethyl alcohol‚ through the oxidation of the 2 NADH molecules‚ which returns them to two NAD+’s (Freeman‚ 2011). Oxidation is the loss of an electron in this case H+. We used information from previous labs in which we tested

Recipe # 1: (one batch) We turned the regular oven on to 375 F. We used two steel bowls‚ one for liquid ingredients and one for dry ingredients. Also‚ we used measuring cups‚ spatulas‚ measuring spoons‚ whisk‚ electric mixer machine. The ingredients we used were all-purpose flour‚ sugar‚ tablespoon vanilla‚ half vegetable oil and half margarine‚ egg‚ little bit salt‚ baking powder. Next‚ we combined sugar and butter in a bowl‚ and we mixed the ingredients with a hand whisk until there

You are also responsible for the PowerPhys lab report. Measuring Normal Respiratory Volumes 1) Calculate the minute respiratory volume using the tidal volume and breaths per minute (pump rate). 2) Define the following terms: a. Respiration- The act of breathing‚ inhaling and

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and

Measuring of Lung Capacity Introduction This lab report is over the functions of the lungs and a better understanding of how the respiratory function happens within your body. You will be measuring the amount of air you breathe in and out. This function is called tidal volume‚ which is about 500 cc of air. Second portion of the testing procedure will be determining the amount of vital capacity or maximum amount your lungs can expel. You will be working in pairs with a lab partner and take turns recording

Succession Lab INTRODUCTION: The purpose of our lab was to begin to understand the rates of succession. Succession is a number of persons or things following one another in order or sequence. Considering that all living things follow some sort of order‚ Joey Collins‚ Brian Carman‚ Chris Broadwater‚ Marisa Grondin‚ and I attempted to figure the succession rates of two different forests. In order to do this we used the forest behind the elementary school and the forest behind the track‚ by the

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the
