    attaining methodologies. Using a lactose tolerance test the arbitrary cut-offs are difficult when taking into consideration borderline values. The impact of certain cut-offs would eliminate or include participant values that could impact on the big picture of the results. For breath hydrogen analysis and lactose tolerance test, another error is the likelihood of false positives and false negatives. Most commonly is found in studies is that breath hydrogen reveals the most accurate results (Mulcare, C

    Tables: Hydrogen Step B: Describe the zinc and acid reaction. As placing a small piece of Zn(mossy zinc) metal into the test tube containing the diluted HCI(Hydrochloric Acid) solution, gas bubbles rose from the solution slowly at the beginning and vigorously in process of time. As this reaction continued for a long time, transparent solution turned into white opaque color and black precipitates were formed and floated. Step G: Record your observations with the flame and the hydrogen gas. When

    Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases, and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles, test tubes, 24 well plate, Gas assembly with copper and plastic tubing and a #00 stopper, short stem pipet, rubber stopper #00 with one hole and a pipet tip with

A hydrogen breath test is also indicated to determine if excess hydrogen is in the bloodstream from bacterial overgrowth or malabsorption (Roberts, 2013). If the provider decides to implement the hydrogen breath test, the client will need to remain NPO at least 12 hours prior to the exam, excluding sips of

    The first unknown test tube P found to be a gram positive bacteria. The biochemical that I performed that were positive were catalase and blood agar. Catalase has the presence of an enzyme in the test isolated detected using hydrogen peroxide. Bacteria possess catalase with a small number of bacteria; isolation is added to hydrogen peroxide when bubbles occur. When the bubbles occurred on gram positive bacterium it was a conformation of being positive. Also, blood agar plates is useful for cultivating

    magnesium. Introduction: Chemistry happens everywhere, not just in a lab. Matter interacts to form new substances through a process called a chemical reaction. Your body lives and grows because of chemical reactions, whether by taking medicine or even a breath. A chemical reaction is defined as the process that involves rearrangement of the ionic structure of a substance. A reaction rate is how fast or slow a reaction takes place. Chemicals that proceed quickly have a fast reaction rate, whereas slowly
