INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

Chemistry 2: Organic and Inorganic Chemistry Activity 1 PROPERTIES OF ORGANIC COMPOUNDS (Sugar) Rainbow Density Column Introduction As a chemical term‚ “sugar” usually refers to all carbohydrates of the general formula Cn(H 2O)n‚ an organic compound. This exercise is focus on sugar as an organic compound and its properties. Objectives: 1. To identify the properties of organic compound - sugar. 2. To observe some physical properties and changes on an organic compound during the actual conduct of

ORGANIC AND INORGANIC CONSTITUENT IN ESSENTIAL IN PLANTS AND NUTRIENTS REQUIRED TO PLANTS Organic constituent DEFINITION An organ‚ system‚ or other discrete element of an organism the part of the plant that carries out photosynthesis. EXPLANATION: The chemical compounds of living things are known as organic compounds because of their association with organisms. Organic compounds‚ which are the compounds associated with life processes‚ are the subject matter of organic chemistry. Among the numerous

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam and

Experimental Objectives In experiment #1 the main objective is to test the solubility and the strength of the ionic compounds that are formed during titration. Solubility is a measure of the degree at which a compound is able to dissolve. Titration is used in this experiment to determine the Ksp of the saturated solution of Mg(OH)2 Ca(OH)2 SR(OH)2. Procedure and Observations Saturated solutions of Mg(OH)2‚ Ca(OH)2‚ and Sr(OH)2 are all prepared in which they need to be diluted with distilled

Without using electricity‚ there are many ways to illuminate a parking lot. First‚ I can decorate the ceilings and walls of the parking lot with glow sticks (light sticks). This method of producing light is called chemiluminescence. Chemiluminescence is the direct production of light as the result of a chemical reaction with little or no heat produced. The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester

Synopsis The purpose of this experiment was for students to prepare some simple organic compound and to purify the compound by recrystallisation. This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc

relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United
