Suggested time allotment: 5 to 6 hours MODULE 2 ACIDS AND BASES In Module 1‚ you identified common properties of solutions using different methods. You learned how to report the amount of the components in a given volume of solution. You also found out that not all solutions are liquid. Some of them are solids and others are gases. Towards the end of the module‚ you investigated the factors that affect how fast a solid dissolves in water. Most of the solutions you studied in Module 1

Outline and evaluate Bowlby’s theory of attachment (12 marks) Bowlby was an evolutionary Psychologist who believed that attachment is a part of evolutionary behaviour and focus on an animal’s instinctive and innate capabilities‚ and the functions of their behaviour. They believe this is useful for learning about human instinctive and biological behaviour. Attachment behaviour keeps a young animal or human safe. It is behaviour seen in all species of animal. Many species of animal form rapid attachments

Discuss Bowlby’s work on attachment. Refer to the work of at least one other researcher in your answer. (12 marks) Attachment theory was developed in the 1950’s by psychoanalyst John Bowlby‚ who defined attachment as a ‘lasting psychological connectedness between human beings’. Whilst working with James Robertson in 1952‚ he observed that children experienced intense distress when separated from their mothers and if fed by other caregivers‚ the child’s anxiety did not diminish. This led to his theories

Bases of Power According to Robbins & Judge (2007) power is defined as the “capacity that A has to influence the behavior of B so B can act with A’s wishes.” There are five bases of power that are divided into two groups according to Robbins & Judge (2007). Formal Power The first group in the power in the power bases is formal. Formal power is based on the position held in organization (Robbins & Judge (2007). Formal Power is divided into three power bases: coercive power‚ reward power

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.
