If 4.168 kJ of heat is realsed be a reaction inside a calorimeter containing 75.40 g of water, the temperature of the water as well as the calorimeter increases from 24.58C to 35.82C. Compute the heat capacity of the calorimeter (in J/C). The specific heat of water in 4.184 J/gx C
The atomic mass of chlorine is listened as 35.454 amu on the periodic table. It has two naturally occuring isotopes CL 35 and Cl 37. What are the approximate percentages.
If you used 20 ml water to recrystallize salicylic acid at 10 °C, estimate the amount of product that can be lost as a result of dissolving in the filtrate. (solubility at 10 °C =0.14/100 ml water). Calculate the loss if you had used 4 mls of wate..
