Chemiluminiscence Experiment Lab Report Example | Topics and Well Written Essays - 750 words

Chemiluminiscence Experiment - Lab Report Example This undertaking involves the use of dissimilar concentrations of luminol and at varied temperatures (Roda 51). The experiment requires various chemicals and apparatus in order to become successful. About 25 ml of chlorine in liquid for will be useful as an oxidizing agent (Roda 53). Quantities of water of half liter will be desirable in the process together with 0.12 grams of luminol. Beakers will be in use for putting the reagents of the experiment. A beam balance will perform various measurements, which are suitable, for this experiment (Roda 53). An ice bath and a thermometer for aiding temperature measurements are fundamental. Other materials will involve a funnel plus a plastic tube. The procedure for the experiment involves measuring 0.12 grams of luminol by using a beam balance and mixing the mass with 250 Ml of water in distilled form (Roda 53). The action results in a solution of luminol. While measuring the luminol substance, a minimum of three measurements are significant for providing accurate measurements. This is possible by conducting about three measurements and finding the differences in mass. There should be a consideration of the mass of the paper that will contain the luminol substance in order to maintain accuracy (Roda 55). Maintaining accurate measurements is critical in reducing errors in experiments or deviation from the expected results. The next step will involve production of the bleach contents. It entails performing a mix of 25 ml of chlorine bleach in liquid form and about 225 ml of water in distilled form. The bleach and the luminol solutions are cool in an ice bath and the temperatures put in the record. The recording is for both solutions put in separate containers (Roda 55). Darkening the room will ensure efficiency in performing observations, especially, the amount of light seen when the two solutions come in contact. A funnel linked with the plastic tube will be present to

Health promotion theroy Coursework Example | Topics and Well Written Essays - 250 words

Health promotion theroy - Coursework Example This theory is normally based on the fact that the readiness of an individual to act depends on his or her own perceptions. These perceptions include severity of the consequences, the potential benefits, and cost of taking that particular action as well as the susceptibility. The main advantage of this theory is that subsequent interventions can be planned and made on the basis of the response of an individual towards these concepts. This theory was purposely developed to respond to the issue of the failure of the free TB health screening plan. This model can be used to look into a number of both short-term and long-term health behaviors which include the transmission of HIV/AIDS and other sexual risk behaviors (Glanz & Lewis, 2002). This theory argues that a person will normally take a health-related act such as using a condom if he feels that HIV can be avoided, expects a positive result by using protection and if he believes that he can effectively take an optional health action. This theory is very useful when planning for the community health program. You will be in a position to predict the proper plan of action to take after taking these studies in the community. However, it is worth noting that the theory does not look into other aspects of the individual such as the environment in which they live (John,
