Experiment 19 - Determination of the equilibrium constant for the reaction Fe3+ (aq) + SCN( (aq) = FeSCN2+ (aq) Object: To determine the equilibrium constant by a colorimetric method Theory: Colorimetric methods of analysis are usually applied to the determination of small concentrations of either inorganic or organic materials in a solution. The constituent sought must be coloured or must be capable of reacting with a reagent to produce a substance having a suitable colour. Beers Law‚ which

1. Compare the replication cycles of H1N1 and Herpes simplex. -Herpes (DNA) and H1N1 (RNA) viruses both multiply in the cells cytoplasm. The major differences among the multiplication process of these viruses lie in how MRNA and viral RNA are produced. The sequence is as follows (1 and 2) are: Entry‚ uncodeing the viral DNA/ RNA (replication). (3) Transcription of a portion of the viral DNA. Translation follows (resulting enzymes) for multiplication of DNA/RNA. Most cases of DNA viruses early

environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations were determined by spectrophotometry using the 3‚ 5 dinitrosalicylic acid (DNS) method. The first sample was operated as blank for zero. The stock solution was prepared in order to find the unknown concentration of carbohydrate cereals powder‚ jam (total sugar content) and jams (reducing sugar content). The absorbance

EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD METHODOLOGY The concept of increasing the fuel efficiency of a petrol engine in this project‚ is to pre-heat the intake air which is flowing through the carburetor. The humidity in the atmospheric air affects the petrol vapourisation in the carburettor. Therefore‚ by pre-heating the inlet air to the carburettor for a considerable amount‚ the vapourisation can be ease and in turn
