Double Replacement Lab Report

If this does occur remove any contaminated clothing and rinse the skin and clothing thoroughly. • Do not inhale chemicals as they can be poisonous. If this does occur take the person away from the substance and take them to a hospital immediately. Method To test my hypothesis, I will add varying amounts of Strontium Nitrate (1-8cm³, adding an extra 1cm³ each time) to 8cm³ of Sodium Nitrate in order to form a white precipitate.

Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

1. The test subjects will prepare for sleep by acquiring everything needed for the subjects’ sleep preferences. 2. The test subjects will all set alarms on their smartphones for approximately 6, 8, and 10 hours after the subjects’ enter the resting period (Subjects may wake during the resting period for the bathroom, but they must not stay awake for more than ten minutes at a time to prevent as much deviation as possible.). 3.

1. Identify the range of senses involved in communication • Sight (visual communication), Touch (tactile communication), Taste, Hearing (auditory communication), Smell (olfactory communication) 2. Identify the limited range of wavelengths and named parts of the electromagnetic spectrum detected by humans and compare this range with those of THREE other named vertebrates and TWO named invertebrates. Figure 1: the electromagnetic spectrum source: www.ces.fau.edu Vertebrates Human Japanese Dace Fish Rattlesnake Zebra Finch Part of electromagnetic spectrum detected ROYGBV (visible light) detected by light sensitive cells in the eye called rods and cones.

14.Both. They can help with reconstruction later. 15.Bloodborne pathogens 16.You should wear neoprene gloves for bases and polyvinyl chloride gloves for oils. 17.This is when you are required to treat all blood or bodily fluids as if they are infected.

When dealing with substances, they will have a potential hazard which can affect the health care setting. The substance can be a potential hazard in the residential care home as there is clinical waste and cleaning products. As the nurse and the staff member will have to make sure that the cleaning products is locked in a room so that the visitors and the residents won 't be able to go in and touch the chemical products. There is a law called COSHH Regulation 2005, which stand for Control Of Substance Hazardous to Health regulation 2005. COSHH is when the hazardous substance have to be handled in a right way and it has to be stored in a minimise risk which is present.

Use safe, precautions are to be followed by the chemicals that stay inside of the glow stick. The packaging on the glow sticks says that they are non-toxic. Do not puncture or cut the plastic cover off of the glow sticks. The glow sticks contain chemicals. There are no dangerous chemicals, but they should be handled with respect.

Some of the more common hazards include exposure to disease and infection from corpse tissues and other bodily remnants. There is also a risk of skin contact and inhalation of hazardous chemicals like formaldehyde, which is used to preserve the body and its parts, or even chemicals used to disinfect the autopsy equipment. Occasional exposure to radiation from x-rays used to see if there are foreign objects in the body like bullets and the bone structure of a corpse. Forensic pathologists are taught to use precautions such as gloves, surgical masks, lab coats, shoe coverings, plastic aprons, respirators, arm protectors, goggles, and hair coverings, but there is still an element of risk (Mandel). Stress can increase the chances of mistakes and negligence and in turn, can result in any of the bodily harms listed.

When working as a chemical technician you work in a laboratory most of the time. Chemical technicians set up the laboratory equipment, such as mass spectrometers and simple laboratory glassware, required for the tests and experiments they do. The jobs of a chemical technician also require that they do require maintenance on the equipment. In experiments where airborne toxins or temperature may affect the results of an experiment, they maintain the required conditions in laboratories. Such as dust and toxic free “clean rooms” and refrigerated spaces.

And if the pressure in the skin's pores gets too high, it will become full on inflammation, rupture the pore and spread to the next pore, spreading the problem across your skin. Okay so let’s get to the ingredients oftentimes used in the skin care products, that you may want to be avoiding: Silicones Names: Methicone, dimethicone, trimethicone, cyclomethicone, siloxane, cyclopentasiloxane, cyclotetrasiloxane, cyclohexasiloxane, silsesquioxane, trimethylsiloxysilicate, methylpolysiloxane, stearoxytrimethylsilane What they are supposed to

Experiment 2 Report Scaffold (Substitution Reactions, Purification, and Identification) Purpose/Introduction 1. A Sn2 reaction was conducted; this involved benzyl bromide, sodium hydroxide, an unknown compound and ethanol through reflux technique, mel-temp recordings, recrystallization, and analysis of TLC plates. 2. There was one unknown compound in the reaction that was later discovered after a series of techniques described above.

Carefully take out your power drill. 2. Make sure you are not around the water or children. 3. Wearing baggy clothes, loose sleeves, jewelry, and hair can be a hazard.

The GOOD NEWS is that the number one protection for your pet to prevent distemper is vaccination. HEPATITIS H is for Hepatitis Canine Infectious Hepatitis is caused by a virus known as an adeno (add-en-oh) virus—type 1, to be more specific: CAV-1 (canine adeno virus type 1). Canine Hepatitis virus magnified Hepatitis is spread from pet to pet by contact with infected feces, urine, blood, saliva, and nasal discharge. Dogs may also be infected by wolves and coyotes.

Mercury compounds are readily absorbed through the skin on topical application and have the tendency to accumulate in the body. These products are often applied to large areas of the skin, left on the skin for hours at a time, and used repeatedly for weeks, months or years. Mercury-containing skin lightening cosmetics pose significant risks to users. Mercury absorbed through the skin from lightening products can damage the skin itself, the kidneys, and the nervous system.
