If High purity benzoic acid [C6H5COOH; H(rxn) = -3227 kJ/mol] is a combustion standard for calibrating bomb calorimeters. If an unknown quantity of the benzoic acid is burn up in the calorimeter (heat capacity = 1365 J/C) containing exactly 800 g of water also results in a temperature increase of 5.62 C, explain how many moles of the benzoic acid was burned?
Calculate the average translational kinetic energy (sometimes just called average kinetic energy) for one mole of gas at 385 K.
signs made from glass tubes filled with _________ and argon gases can light up when electricity is passed through them.
As a technician in a large pharmaceutical research firm, you need to produce 100 mL of 1.00 M potassium phosphate solution of pH = 7.00. The pKa of H2PO4 is 7.21. You have 2.00 L of 1.00 M~ KH2PO4 solution and 1.50 L of 1.00 M~ K2HPO4 solution
In a calorimetry experiment, 0.497 g of potassium hydroxide are dissolved in 25.o ml of water (density = 1.00 gml, specific heat = 4.184 j g-1 °c-1) in an insulated container. the temperature of the water rises from 21.37 °c to 26.25 °c.
