Cu(s)+2Ag+(aq)->Cu2+ +2Ag Conclusions: Zinc is the strongest reducing agent. Zinc loses electrons most easily and is therefore oxidised. After zinc comes lead‚ followed by copper‚ while silver has least reducing ability of the metals studied in this lab. The reducing ability of the metals was arrived at from the observations of patina formation on the metal plates. If the positive metal ions in the solutions are less powerful reducing agents‚ then the metal in the plate will be reduced and hence form

Introduction Reduction/Oxidation (Redox) reactions are ones that change the oxidation state of a compound. The oxidation state refers to the acquired charge (gained or lost electrons) of an element in relation to its original charge (i.e. S + 2e- S2+); in a compound‚ the overall oxidation state is calculated by adding all the charges of the elements present. The addition of electrons makes the element “reduced” and the loss of electrons is called “oxidized”. These reactions can be carried out in lab‚ or

Running head: RESEARCH PAPER Harm Reduction and Substance Abuse Liberty University Abstract This paper examines how harm reduction is a theoretical model which has been proposed to address the harm which is caused by the behavior of an individual‚ not only to themselves‚ but also to the wider community. In particular‚ it looks at how the model has also provided a potential framework for dealing with substance abuse‚ and has been adopted in practice in many countries around the world. This

four decades‚ and poverty reduction has been much slower than in neighboring countries such as the People’s Republic of China‚ Indonesia‚ Thailand‚ and Viet Nam. Economic growth has gone through boom and bust cycles‚ and recent episodes of moderate economic expansion have had limited impact on the poor. Great inequality across income brackets‚ regions‚ and sectors‚ as well as unmanaged population growth‚ are considered some of the key factors constraining poverty reduction efforts. Poverty and inequality

The uncertainty reduction theory was created with intention of giving an explanation to an everyday occurrence when encountering new people. The theory gives reason to something everyday people experience regularly without consciously thinking about it. Psychology had attempted to explain the emotional process of first encounters but never like this. Although a lot of thought and consideration had been put into this‚ there was no way it could consistently cover every aspect it addresses. Diving further

presence of a reinforcement can motivate an individual to repeat the behaviour more frequently. Drive-reduction theory argues that a primary or secondary drive motivates an individual to perform actions that will reduce the drive (Burton‚ et al.). Reduction of the drive is a form of reinforcement leading to the individual repeating the action more frequently (Burton‚ et al.). According to the drive reduction theory‚ sleep is a primary drive which is reduced‚ and thus‚ reinforced by the act of sleeping
