Cocaine(C17H21O4N) is a natural substance found in the leaves of the coca plant, which has been used for centuries as a local anesthetic and stimulant. Illegal cocaine arrives in the USA either as a pure compound or as the hydrochloride salt(C7H21O4NHCl). At 25 degrees celsius, the salt is very soluble in water(2.59kg/L), but pure cocaine is much less so(1.70g/L) a. What is the maximum amount of salt in grams that can dissolve in 50.0mL of water? b. When a 25mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water in liters is needed additionally to dissolve the formed pure cocaine,

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…
