Answer:
<em>Ethnocentrism is a normal reaction in taken pride in the success of your ethnicity but destructive when taken too far as to want to destroy other perceived lesser ethnic group.</em>
<em></em>
Explanation:
Ethnocentrism is the belief in the superiority of one's culture over others. Ethnocentrism is associated with the pride of falling into a particular culture, and is a learned behavior passed down from parents and society to the young ones among them. Ethnocentrism can be considered a normal reaction, when one finds oneself as a member a group that seems to have excelled in a particular way of life. Example is the feeling of pride that comes with your country winning the FIFA world cup; and its only natural to demonstrate ethnocentric characteristics in this case. A destructive effect of ethnocentrism can be demonstrated through genocide; in which a particular ethnicity rises up to destroy violently another perceived lesser ethnic group. This wrong ethnocentric drive has been a reason for the loss of millions of life globally.
Explanation:
1. The three factors are;
- Increasing the surface area of the reactants
- Using a catalyst
- Increasing temperature
2. Raising the temperature of a reaction mixture is the same as increasing the kinetic energy of the reacting molecules.
3. This reaction is an exothermic reaction. In exothermic reaction, the temperature of the system (mixture) decreases while that of the surroundings increases.
4. Reactions that releases energy to the surroundings are exothermic reactions.
5. All the options is an example of exothermic process because heat is being removed from the system except;
B. Evaporation of water - This is because it must absorb heat from the surroundings making it endothermic.
