experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get

For the research question examined‚ is what the correlation between parental addictive behavior and the effects on their preteen children? Utilizing qualitative research is an affective way to gather actually data on the sample subjects. The data collection strategy used will consist of purposeful sampling. Purposeful sampling examines those that have experience in the area that is being studied and are able to verbalize these experiences in a descriptive and detailed manner (Kostere‚ 2016)

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

A qualitative study on Sri Lankan women living in the UK- A perspective on culture‚ exercise and dietary patterns. 1.1 DESCRIPTION OF THE APPROACH Having read the transcripts and the aim of the research‚ I decided to choose which qualitative approach to use in the analysis. Grounded Theory was ruled out because it deals more with a sociological approach and works better with a larger sample group (Willig‚ C‚2009). Discourse Analysis explores the role of language in participant’s descriptions of
