Adverse drug reaction

In the scientific world, there is a significant difference between calculated values and values measured in investigations. Percentage Yield is the ratio, between masses, of the actual yield to the theoretical yield. The actual yield is the amount or mass of product actually collected during an experiment or industrial process, while the theoretical yield is the amount or mass of product predicted based on the stoichiometry of the chemical equation. In order to calculate the theoretical yield,…

Scenario 1 describes the reaction that takes place between H2 and I2 to form the acid HI. This reaction involves very intricate and steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions…

the quantitative branch of chemistry, called analytical chemistry, which aims not just to determine the component but also to quantify the amount of the component in the sample. Redox titration is an analytical method which is based on a chemical reaction between an oxidizing agent and a reducing agent. Permanganimery is a common redox titration component because of its high standard reduction potential, making it a good oxidizing agent. Permanganate reacts with oxalic acid according to Equation…

The GCMS analysis showed the metabolites could be definitely identified as concern compound by comparisons with known authentic compound. The m+ ion is found at m/z94 for phenol. The molecular weight of the phenol is 94. The base peak value of phenol was observed as 94 and mass peak values were recorded as 66, 39, and 55. The m+ ion for acetophenone is m/z 120. The molecular weight of the compound was observed as 120, the base peak and mass peak values were recorded as 105 and 91, 77, 51, 39,…

Michael is an IG2 chemistry student. He has to his disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of…

Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

oxidation-reduction reaction or redox reaction. Oxidation is also the gain of oxygen and loss of hydrogen while reduction is the loss of oxygen and gain of hydrogen. Redox reactions occur in everyday life, it is a highly significant form of chemical reaction. Examples of real life redox reactions include: combustion, metabolism of food, biological processes as well as the rusting of iron. Combustion- The burning of a substance causes it to react with oxygen in the air. Redox reactions occur…

combustion reaction tends to be less complete. The bigger the molecule of alkenes, the more likely to get a yellow, sooty flame. B. Action of sulphuric acid (to be performed under fume hood) 1. When concentrated sulphuric acid was added into cyclohexane, is there any sign of reaction? Ans: No. 2. Do the substances mix or are there two separate layers in the test tube when concentrated sulphuric acid was added into cyclohexene. Explain the reason behind the reaction. Ans:…

Thus only NB atom can be protonated. Gabriel Amine Synthesis (Preparation of 1o amines) The Gabriel Amine synthesis is a three-step organic reaction that converts an alkyl halide to a primary amine. The advantage offered by Gabriel Amine synthesis is that it avoids poly-alkylation. Step 1: acid-base reaction. The acidic phthalimide molecule gets deprotonated by a strong base. The strength of an acid depends on the stability of the conjugate base. The negative charge on…

Discussion Graph 1 displays the reaction time (in minutes) of how long it took for the Alka-Seltzer tablet to completely dissolve per trial. Graph 2 displays the averages of the reaction time which showed the higher the water temperature is, the faster the reaction time would be. At 65⁰C the average time for the Alka-Seltzer to completely dissolve was 1 minute 4 seconds followed by 1 minute 20 seconds at 35⁰C and ending with the highest average at 2 minutes 1 second (1.61). The hypothesis…
