RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

The Tiv-Jukun Ethnic Conflict and the Citizenship Question in Nigeria Moses T. ALUAIGBA Aminu Kano Centre for Democratic Research and Training‚ Bayero University‚ Kano Abstract The negative consequences of the Tiv-Jukun ethnic conflict and other similar conflicts in Nigeria have stimulated the debate on citizenship in the country. This debate is driven by questions that hinge on contestable issues such as who is an indigene in Nigeria‚ why should other Nigerians be termed non-indigenes‚ settlers

“Peace is not absence of conflict‚ it is the ability to handle conflict by peaceful means‚” this quote by Ronald Regan shows that conflict is an inevitable part of society. Conflict is a fundamental part of life and is always present for every individual throughout their everyday life. Encountering conflict means to face or handle conflict and the ways in which we go about trying to resolve it. Different types of conflict can be local‚ national‚ religious‚ political‚ economic or cultural. There are

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

Introduction Conflict usually occurs primarily as a result of a clash of interests in the relationship between parties‚ groups or states‚ either because they pursuing opposing or incompatible goals. Although the term war is sometimes used as a synonym for conflict‚ it is more usual to restrict the meaning of war to violent conflict‚ involving armed forces. But like war‚ conflict is and has been throughout history a normal way of conducting disputes between political groups within human society

Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement reaction‚ double-replacement reaction‚ and combustion reaction. Combination

THE TYPES OF WARS Introduction 1. War has numerous forms‚ faces‚ and shades. In today’s political environment‚ it is difficult to say‚ precisely‚ where peace ends and war begins. Classification of wars is discussed in the following paragraphs. Classification of Wars 2. Coercion. It is the Active use of force in a measured way or threat of force to persuade an adversary to adopt a certain pattern of behaviour against his wishes.

Conflicts occur when people (or other parties) perceive that‚ as a consequence of a disagreement‚ there is a threat to their needs‚ interests or concerns. Although conflict is a normal part of organization life‚ providing numerous opportunities for growth through improved understanding and insight‚ there is a tendency to view conflict as a negative experience caused by abnormally difficult circumstances. Disputants tend to perceive limited options and finite resources available in seeking solutions

The Nature of Conflict Conflict: Varied Perspectives; Belief Systems and Values; Interests There is‚ perhaps‚ nothing more common than conflict. As a mediator‚ conflict may constructively be viewed as resulting from: • varied perspectives on the situation; • differing belief systems and values resulting from participant’s accumulated life experience and conditioning; and • differing objectives and interests. Effectively dealing with conflict requires the expression and management of
