Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

points A 0.1938 g of an organic compound known to contain C and H only was burned. The traps for H2O and CO₂ increased in mass by 0.2750 g and 0.5972 g. respectively. What is the percentage of carbon?
62 Ammonium dinitramide (ADN), NH4N(NO2)2, was considered as a possible replacement for aluminium chloride as the oxidizer in the solid fuel booster rockets used to launch the space shuttle. When detonated by a spark, AND rapidly decomposes to produce a gaseous mixture of N2,O2, and H2O. (This is not a combustion reaction. The ADN is the only reactant.) The reaction releases a lot of heat, so the gases are initially formed at high temperature and pressure. The thrust of the rocket results mainly from the expansion of this gas mixture. Suppose a 2.3-kg sample of ADN is denoted and decomposes completely to give N2,O2, and H2O. If the resulting gas mixture expands until it reaches a temperature of 100°C and a pressure of 1.00 atm, what volume will it occupy? Is your answer consistent with the proposed use of ADN as a rocket fuel?

1.1 It is well-known that te emission of greenhouse gasses such as carbon dioxide presents a very grave threat to the environment. Attempts are ongoing to absorb this gas by several means. One such approach involves the use of vegetation, as plants utilize the gas by means of photosynthesis. One such plant , which has shown great promise, is the "Spekboom" It has been estimated that fully-grown Spekboom can absorb 3.8 tonnes of carbon per hectare of plants per year. If the system is fully functional, South Africa can generate 234.5 x 109 kWh of electricity per year. Assume that 1559 pounds of CO2 is emmited per year per Megawatt-hour of electricity generated in the country. Determine, by means of the use of conversion factors, how many square kilometres of Spekboom could theoretically absorb all of this carbon dioxide ? 1.2 Consider the molecule, ClPO2 (The Phosphorus atom is the central atom) 1.2.1 Draw the 3-D Lewis dot structure of the molecule, including all possible resonance…
