was to identify the unknown white compound. The chemicals used the 1st day of the lab contain 1mL of 0.1M AgNO3, 6M HNO3, 6M NaOH, 0.1M BaCl2 and 1 mL of 6M HCl these chemicals were specifically chosen for the ion tests after the unknown dissolved in water, as mentioned on lab archives. In our entire experiment we used distilled water because routine tap water can produce many problems when used in sensitive lab like this. Distilled water is used because it is important to eliminate ions and minerals
What is iodide? Iodide is a form of iodine that is a slightly different atomic charge and it is chemically bound with an element like potassium or sodium (Dr. Group, 2013). Iodide is the ion state of iodine, this happens when iodine bonds with another element. Iodides are simply a safe form of iodine for people to eat. When you purchase iodine from the store, it is usually in a form of iodide solution like salt. This allows the body to take the iodine in your body and use it safely. Iodine is
and thoughtful Sarah: Very irritating, cool and easy going, party – wild and quite talkative Michaela: Very bold and outgoing – party girl (Starts: Theme: Henry Mancini – The Pink Panther Theme) Dianna looks in distress and walks into a science lab, trying to be unnoticed. She sneaks in to do her work avoiding Sarah and Michaela. She consistently drops her books as she is nervous, trying to escape
have become accustomed to. I clarify that an audiologist is responsible for the diagnosis and treatment of various ear irregularities including hearing loss or balance disorders. These state-certified clinicians can work with people ranging
Firstly, safety goggles and lab coat must be worn throughout the experiment to avoid any chemicals direct contact with any part of the body. Gentle care must be taken when handling pycnometer because it is expensive and fragile. The pycnometer must be empty and dry of the outside
(t=0) water (Tw0) and inner condensing cover (Tci0) temperature and assumed to be constant over 0-t time interval. Hence, hte and htw have been considered constant over 0-t time interval. After making the above assumptions, Eq. (7) becomes first order simple differential equation. The solution of Eq. (7) with initial condition, Tw = Tw0 at t=0, becomes And inner and outer glass cover temperatures obtained from Eqs. (1) – (6) are: …... (9a) …… (9b) The obtained values of water and
The group decided to violate the social norm surrounding simple walking – we decided to walk backwards for a period. It’s physically the best way to walk, with regard to keeping balance and watching where one walks. As such, everyone walked in this manner, save for the occasional Purdue Office of Admissions tour guides. Nobody thinks twice about how to walk. Our research, then, seeks to violate the norm of walking “forward” and observe the reactions of individuals, both strangers and acquaintances
Anatomy, and Physiology, this field need people to be dedicated and willing to be a full time student. According to American Physical Therapy Association, approximately seventy-five percent (75%) of the PTA curriculum comprises classroom (didactic) and lab study and the remaining 25 percent (25%) is dedicated to clinical education. PTA students spend on average 16 weeks in full-time clinical education experiences (“Physical Therapist Assistant (PTA) Education Overview”). The whole idea of the program
6-sided monosaccharides. Lactose is a sugar found in milk as well as many other dairy products and is the substrate in the reaction. To digest lactose, the lactase enzyme reduces the energy needed for the hydrolysis of the disaccharides into its two simple sugars. Enzymes, such as lactose, are proteins and can be
INTRODUCTION Photosynthesis is a chemical process in which plants, algae and certain bacteria produce oxygen and glucose using the energy from the sunlight. This process is important for life because of the oxygen and glucose released; these products are used in many life processes. Photosynthesis takes places in a wide variety of organisms and also comes in different forms; these include a form of photosynthesis that does not produce oxygen which is called anoxygenic and the other form which does
