In chemistry, compounds can be distinguished by using the empirical formula. The formula provides the simplest positive integer ratio of elements in a compound. The empirical formula is largely useful in determining the ratio of elements within ionic compounds where the structure is of a non-directional nature of bonding where any ion at any time could be surrounded by 4, 6, or 8 oppositely charged ions. This creates a pattern of endlessly repeating lattice of ions they do not exist…...

The dissociation of protons from oxalic acid proceeds in a stepwise manner as for other polyprotic acids. Loss of a single proton results in the monovalent hydrogenoxalate anion HC2O4−. A salt with this anion is sometimes called an acid oxalate, monobasic oxalate, or hydrogen oxalate. The equilibrium constant (Ka) for loss of the first proton is 5.37×10−2 (pKa = 1.27). The loss of the second proton, which yields the oxalate ion has an equilibrium constant of 5.25×10−5 (pKa = 4.28).…...

Farmers in Medieval times did not have tractors or farm machines as we do today. All that a farmer needed was a horse or ox, a wife and a plough. The mould-board plough was invented after the fall of the Roman empire by Slavic tribes. This complicated device was made out of metal and wood. The design allowed six or more oxen to pull the plough which was used to break up ground, or heavy, clay burdened soils. The second…...

The oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within its three main reservoirs: the atmosphere (air), the total content of biological matter within the biosphere (the global sum of all ecosystems), and the lithosphere (Earth's crust). Failures in the oxygen cycle within the hydrosphere (the combined mass of water found on, under, and over the surface of a planet) can result in the development of hypoxic zones. The main driving factor of the oxygen cycle…...

Trees occupy an important place in the life of man. The trees provide us flowers, fruits, fodder for animals, wood for fire and furniture and provide cool shadow from scorching sun. They give us so many such good things and yet expect nothing in return. Trees give us fruits for food and flowers for pleasure. They provide us timber (wood) for building our houses and making furniture. They provide us wood for fuel. They supply sleepers for the railway line.…...

The determination of the oxidation state of a carbon atom can be used to find a change in the oxidation state. The rules used assign carbon a formal oxidation state based on +1 for any atom less electronegative than carbon, -1 for atoms more electronegative, and 0 for C-C bonds. The carbon must bear an oxidation number that makes this sum equal zero. Increasing the oxidation state or oxidation number of the carbon atom is called an oxidation reaction. This…...

1. Based on the dissolved oxygen values for the three distilled water samples at different temperatures, it appears that there is a relationship between water temperature and DO concentration. It appears based on the averages of the class data that the lower the temperature of the water, the higher the DO concentration, although only to a certain point. There appears to be no significant difference between the DO concentration of the water at room temperature or when heated. 2. The…...

The carbon-oxygen cycles are actually two independent cycles. However, both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis, plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the…...

The objective of the lab was to produce benzilic acid from benzoin. Benzoin was successfully oxidized with nitric acid to form benzil. The percent yield of benzil was 59.26% and the melting point range was 94.1-95.5°C. The literature melting point of pure benzil is 95°C, which indicates the correct product was obtained. Benzil was then rearranged using potassium hydroxide to form benzilic acid. The percent yield of benzilic acid was 57.94% and the melting point range was 147.9-149.8°C. The literature…...

The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid, giving a percent yield of 113.97%. Although the product was allowed to dry for one week, residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much water or not allowing the product to remain in the Hirsch vacuum filtration for…...

Introduction Acidified potassium permanganate is a strong oxidizing agent. It oxidizes substances and reduces itself. MnO4- + 8H+ + 5e- -------------> Mn2+ + 4H2O (Purple) (Colourless) Both iron (II) and oxalate ions can be oxidized. When they come in contact with an oxidizing agent, the following reactions occur: 1. C2O42- ------------------> 2CO2 + 2e- 2. Fe2+ ------------------> Fe3+ + e- (Pale green) (Yellow) So, when potassium permanganate is added to acidified iron (II) oxalate, two redox reactions occur. 1. 5C2O42-…...

This will be repeated until the weight of the test tube with its contents is identical. E. g. 1st reading= 17. 24g, 2nd reading= 17. 18g, 3rd reading=17. 15g, 4th reading=17. 15g The underlined readings are identical; consequently I would stop and record these readings. I would do it like this because when the readings are the same it means that the reaction has stopped and there is no need to go any further. This is done for every amount.…...

The poems, 'Listen Mr. Oxford Don' and 'Half Caste' were both written by John Agard, and in both of these poems, Agard challenges the status quo. In 'Listen Mr. Oxford Don', he challenges the use of language and in 'Half Caste', he challenges views of ethnicity. In the poem 'Listen Mr. Oxford Don', Agard characterizes Mr. Oxford Don as the 'Guardian of English', and the idea of a person who uses the 'correct' form of English. In this poem, Agard…...

During the experiment the crucible used was slightly damaged however did not continue to break or cause any inconvenience to the investigation. For approximately ten minutes, no reaction was visible. The substance contained no odour. After approximately fifteen minutes the piece of magnesium commenced to burn with an overall duration of twenty minutes. When burnt, the magnesium converted to bright orange colour. During the reaction the lid of the crucible was lifted to see any changes or if the magnesium…...

Introduction According to Encyclopedia Britannica, the law of definite proportions is a “statement that every chemical compound contains fixed and constant proportions (by weight) of its constituent elements.” Using experimental data in this investigation, it will determine the percentage composition of magnesium oxide. Chemists believe that the energy released by the synthesis combustion reaction is sufficient to allow magnesium to also react with nitrogen in the air. This reaction produces magnesium nitride. What remains unclear is whether enough magnesium nitride…...

INTRODUCTION: The objective of this experiment was to determine the change in enthalpy when one mole of Magnesium (Mg) reacts with half a mole of Oxygen (O2) to give one mole of Magnesium Oxide (MgO). The balanced chemical equation is as follows: Mg (s) + O2 (g) → MgO (s) ---- ΔHMgO f The reaction between Magnesium and Oxygen to form Magnesium Oxide is essentially the combustion of Magnesium and since every combustion reaction is an exothermic reaction, this reaction…...

Since multiplying the ratio by five gives the closest values to whole numbers, therefore the empirical formula of the oxide is Mg6O5. The third trial was not taken into account because the mass after combustion was not recorded. Uncertainty calculations: The uncertainties for masses in both tables will be: 0.01+0.01=0.02g Table one: Here are the calculations for the uncertainty for the number of moles of magnesium: 0.02g/.10g�100%=20% (the uncertainty for the molecular mass is taken as zero) Therefore the percent…...

It wasn't the most eloquent choice of words, but I could tell Tarela was trying to make a point. So, I waited for her to continue. "What I mean," she sputtered, "What I mean is that you're really smart, but you don't flaunt it. You're chill and not arrogant. You're a contradiction!" Her comment verged on being a compliment. At the time I laughed, not knowing how to handle its intent. My only response arrived late and to my own…...
