# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

Calcium‚ Magnesium‚ and Cytoplasmic Streaming in Physarum Polycephalum Eugenia Rita Lee Dr. Bonner BIO 111 Introduction: Physarum polycephalum is a type of slime mold of the myxogastria class that prefers warm and damp conditions. It can go through three forms‚ plasmodium‚ sclerotium‚ and sporangia. The plasmodium is the primary active state‚ where P. polycephalum consists of protoplasmic veins and multiple nuclei. During this stage‚ the slime mold surrounds its’ food and secretes enzymes

Magnesium: Normal Ranges: 1.7 to 2.2 mg/dL A magnesium test is used to measure the level of magnesium in the blood. Abnormal levels of magnesium are most frequently seen in conditions or diseases that cause impaired or excessive excretion of magnesium by the kidneys or that cause impaired absorption in the intestines. Magnesium levels may be checked as part of an evaluation of the severity of kidney problems and/or of uncontrolled diabetes and may help in the diagnosis of gastrointestinal disorders

Maria Reyes iLab‚ Week #3 ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The purpose of this lab was to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacted with magnesium. In order to measure the atomic weight I needed to measure the amount of the hydrogen gas that was evolved in reaction to the acid of the magnesium. The reaction used was: Mg + 2HCl --> H2 + Mg2+ (aq) + 2Cl- (aq). The major findings of this experiment were that

Lab Report: Effects of Lysozyme Introduction: This report discusses an experiment that was done to demonstrate the effects of lysozyme on populations of Gram positive and Gram negative bacteria. Bacteria have a cell wall composed of peptidoglycan that gives the wall its strength. Gram negative bacteria have and extra component of lipopolysaccharide (LPS)‚ that is stabilized with magnesium ions‚ to their cell wall that further protects them. When Gram positive bacteria are treated with lysozyme

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat of combustion of magnesium by using the calorimeter and a thermometer.

The purpose of this lab was in order to find which combination of two electrodes would produce the greatest voltage‚ under the condition that lemon juice was the electrolyte within a chemical cell. To conduct the lab‚ two slits were created in a lemon‚ which worked as a chemical cell‚ and an assortment of different electrodes were inserted into the lemon. Afterward‚ two wires were attached to each of the electrodes‚ where a voltmeter then gave a reading that was recorded into data. As the experiment
