Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Identifying Dependent and Independent Variables Instructions: For each of the following research designs‚ identify the dependent and independent variables. 1. To investigate the effects of exercise on mathematical problem-solving ability‚ a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising‚ both groups did a set of math problems. 2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis

1. Define state-dependent learning and encoding specificity. Then‚ explain three ways a student might apply these principles to enhance her learning in college courses. Using the results of experimental research‚ state why these suggestions for learning are likely to be successful. State-dependent learning occurs when the physical state of a person such as their internal mood‚ sleep‚ hunger‚ etc. are matched during encoding and retrieval. As for encoding specificity it states the context such as

Overall I enjoyed the counseling the chemically dependent family class. I learned more about family systems approaches‚ and techniques for working with chemically dependent families. Throughout this counseling program we have been learning how to work with individual clients. This class was interesting because it involved the identified client and their entire family‚ while looking at these individuals in a systemic view. Throughout the course we had numerous course assignments to complete. In doing

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional
