Use a new glucose strip and record Data: Conclusion: According to my data, pH levels do, in fact, affect the results of Lactex. I say this because in my experiment, pre-enzyme, my solutions were all negative except for the soda. I used the test strips to determine if they were negative or positive solutions. After I put in the enzyme, Lactex, my results changed. Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme.
Administer a prescribed stool softener as needed (PRN). Jeff requests "something for his headache." Which medication is best for the nurse to administer to Jeff for his complaint of headache? ) Acetaminophen (Tylenol). CORRECT This is the best choice, because Tylenol is a non-opioid analgesic, and it will not cause CNS depression.
These conditions are more suitable for ionic bonds. That is why the sucrose and salicylic acid did not have good results, because they have covalent bonds. There were a few sources of error that could be improved in the experiment. For example, when the substance was poured into the test tubes, some of the compound remained stuck to the weighing paper. If we used a stick resistant material for this step, the whole 1g would be accounted for.
This was so that the mussel samples would not go bad due to heat or harsh solvents. They were extracted with a mild solvent, and then concentrated by evaporation. The team found that the vapor was not toxic, but the residue after was. Other extractions were done to see how the residue separated when added with other mixtures of nonpolar solvents. In the toxic mussels, the visible light absorption spectrum revealed a pattern that was characteristic of phytoplankton pigments.
Lab 5: Precipitate Patterns October 31st, 2013 Partners: Muhammad Saeed, Kristian Palmer and Kyle Poirier By: Rauman Tuan-Kichil For: Mr. Fontaine Investigation: Wastewater from metal manufacturing processes often contains toxic cations. These ions must be removed before the water can be released into the environment. Many of these ions can be removed using precipitation reactions. For example, recycled car batteries contain toxic lead cations, Pb 2+. These can be removed by adding a solution of potassium iodide, KI.
Charcoal vs. Clay Research Project, Section 571, Alejandra Navarro* and Alessandra Thompson * - Primary Author Abstract Two substances – charcoal and Bentonite clay- were tested to determine which item would be a better at adsorbing harmful PAHs (polycyclic aromatic hydrocarbons) that pollute water supplies. Through careful testing, it was proven that charcoal was a better adsorbent than the clay. Both materials adsorbed the model PAH to some extent, but charcoal would be the better choice when selecting which should be used to filter the harmful pollutants out of the water. Introduction In today’s society, water pollution caused by by-products of industrial and agricultural processes is an extremely prominent problem (Schwarzenbach, Egli, Hofstetter, et. al.).
Next the freezing point which didn’t eliminate either of them. Next we look at the mass which was 7.465g/ml. This make me lean toward ethyl ether but the masses were still pretty close. Next we move to the solubility of the substances. They are both very soluble in alcohol and hexane so that doesn’t help, but in water ethyl ether is semi soluble and pentane is in soluble.
The pH level is an indicator of: a) sedimentation b) filtration level c) oxygen levels d) whether a solution is acid or alkaline 35. Clarifying shampoos contain acidic ingredients that: a) reduce dandruff c) are always a good idea b) decrease shine d) cut through product buildup _____ _____ 36. If your client has a dry scalp, the condition may be helped by a: a) hair mask c) protein treatment b) detangler d) scalp conditioner _____ 37. The best method for hair brushing is to: a) brush random areas c) brush the scalp vigorously b) part it into sections d) focus on the ends _____ 38. When you elevate the hair below 90 degrees, you are: a) creating curl c) building weight b) layering the hair d) removing weight _____ 39.
By promoting personal hygiene in your own practice and appearance, and assisting individuals that you care for, you are leading by example. 1.2 Describe the effects of poor personal hygiene on health and well being. Poor personal hygeine can initially lead to the individual developing body odour from either not washing or not changing their clothing, this can lead to the person becoming isolated as family, freinds or the wider community as they are reluctant to spend time with the person. Not keeping their body and skin clean can lead to health problems such as bacterial, fungal or parasitic infections such as athletes foot. Poor dental hygeine will first be indicated by a build up of plaque on the teeth and bad breath but can lead to tooth decay, gum disease and loss of teeth, which can make a person who already has low self esteem loose more confidence.
Personal hygiene is also important as it clears discomfort & odors that might discomfort others & make friends to isolate you. It is essential especially when eating, drinking, sneezing, coughing & sweating to avoid being infected. Good personal hygiene is also important during & after handling all body fluids such as urine, blood or 1.2 Describe the effects of poor personal hygiene on health & wellbeing
