Compare the characteristics of these two gases: Oxygen and Carbon Dioxide. Discuss the uses of oxygen in Medicine/Anaesthesia based on its characteristics.
The solubility of aspirin in ethanol is approximately 40g/100mL at room temperature. If you had 100% yield how many millileters of ethanol would you need to dissolve product for the recrystalization
Explain if you dilute 28.0mL of the stock solution to a final volume of 0.600L, Explain what will be the concentration of the diluted solution
One mole of NOCl gas is added to a 4.0L container. the NOCl undergoes slight decomposition to form NO gas and Cl2 gas. If the equilibrium constant, Kc, for the rxn 2NOCl(g)--->2NO(g)+Cl2(g) is 2.0x10^-10 @ 25 degrees celsius, calculate the concent..
Calculate the molality of ions in a solution made by mixing 5.14 g of CaCl2, MW=110.98, in 79.38 mL of water at 37.0°C. The density of water at this temperature is 0.9933 g/cm3. The answer is 1.76m but I don't know how to get there.
