Concentration of Iron in an Unknown Substance Jack Boswell Experiment 5 Megan Otting and Dr. Caster Introduction: The objective of this lab was to determine the concentration of iron (Fe+2) in an unknown substance using a spectrophotometer. Spectrophotometry is a process that uses a sample solution to determine how much light a chemical substance absorbs by measuring the intensity of a beam of light passing through the solution. Every substance transmits light over a specific wavelength range

disaster prepare is termed “protective steps forever safety” and also consists of building evacuation (“fire drills”), sheltering via significant temperature like tornadoes, “shelter-in-place” via the external airborne danger for instance a chemical substance discharge and also lockdown. Lockdown will be safety actions whenever confronted with the react regarding assault. When a crisis arises, the primary top priority is definitely living safety. Your second top priority would be the stabilization

According to UAB's health website, "Substance abuse is used to describe a pattern of substance (drug) use leading to significant problems or distress such as failure to attend work/school, substance use in dangerous situations (driving a car), substance-related legal problems, or continued substance use that interferes with friendships and or family relationships. Substance abuse, as a disorder, refers to the abuse of illegal substances or the abusive use of legal substances. Alcohol is the most common legal

From the first essay, my knowledge about addiction/chemical dependence has expanded and grown in many levels and ways. One of the most important aspects of substance abuse that gave me a better understanding is dependence and its cause and effect. Although I knew people like experimenting with drugs for many reasons such as out of curiosity, have a good time, peer pressure, and other “compelling” factors. However, for so long I could not grasp why or how some people even among siblings become addicted

Introduction: Water is a chemical substance composed atomically of an oxygen atom, and two hydrogen atoms, giving it the chemical formula H2O . It has a bent molecular structure, with the centralised oxygen atom at the top of the molecule with two lone pairs of electrons above it, and the two hydrogen atoms branching out below, each connected to the oxygen by covalent bonds. VSEPR (Valence Shell Electron Pair Repulsion) Theory is utilised in chemistry for the prediction of a molecules geometry.

attempt to create a Philosopher’s Stone 1743 – 1794 – Antoine Lavoisier established that elements are the fundamental building blocks of chemical substance. He defined an element as ‘a substance that could not be composed into simpler substances. He identified four groups; metals, non-metal, elastic fluids (gas) and earth after examining the physical and chemical properties. 1829 – Johann Dobereiner developed the Law of Triads; the middle element’s atomic weight was the average of the other two elements

Introduction • Chlorine is widely used industrial chemical agent with corrosive properties and a potential weapon of mass destruction. • At standard temperature and pressure exists as Greenish-yellow color gas with suffocating pungent odor. Under high pressure or low temperature, it turns to clear, amber-colored liquid.1 • Chlorine is heavier than air, and therefore it will remain near the ground in areas with little air movement.1 • It is used in water treatment, household cleaning products

Spectrophotometry is an analytical method that measures how much a chemical substance is able to absorb light by measuring the light’s intensity as it passes through a specified sample.3 Given certain wavelengths, the amount of a certain substance in a solution can be determined. The device used to measure these properties is called a spectrophotometer. This device consists of a spectrometer that produces light of any color (wavelength), and a photometer which measures the intensity of the light

Metabolism Definition: The break down and formation of chemical substances in the body that is needed for energy, for formation and breakdown of tissues and cells, and to maintain homeostasis of the body. Concept Key Terms: • Adrenal: endocrine glands that are located on top of the kidneys and are responsible for several hormones like aldosterone, corticosteroids, • Aldosterone: hormone secreted from the adrenal gland to signal the kidneys to retain sodium from the excretion • Autocrine: a hormone

people have turned to substance abuse or experience chemical dependency for a variety of reasons. Nurses experience chemical dependency as well. According to Kunyk (2013), “healthcare professionals, including nurses, are also potentially vulnerable to substance use disorders regardless of any special knowledge, skills or insights they might have owing to their education and professional experiences” (p. 54). This paper will define what chemical dependency is, report causes of chemical dependency in nurses
