The DHvap of ethanol = 39.3 KJ/mol. The boiling point of ethanol is 78.3 C. Calculate the D S for vaporization of 0.5 mol of ethanol.
Write the dissolution reaction for the ionic solids below. Use the lowest possible coefficients. Include states-of-matter under the given
In the preparation of the esters given in this experiment, the reaction product was extracted with 5% sodium bicarbonate solution in the isolation step. Why? What gas was evolved during this washing step? Write a balanced equation for the reaction..
How much heat (in ) is required to warm 10.0g of ice, initially at -11.0(degrees C), to steam at 113.0(degrees C)? The heat capacity of ice is 2.09(J/g* degrees C) and that of steam is 2.01(J/g*degrees C) .
CO (5.00 g) and CO2 (5.00 g) were placed in a 750.0 mL container at 50.0 °C. Calculate the total pressure in the container.
What component of air will bring about this reaction and what is its approximate concentration in air? If you had a stoppered flask with basic luminol and then opened it to the air
Calculate the approximate molarity of this solution from the volume, percent composition, and density.
What is the pH of a solution of 0.20M RbCHO2? Must use an ICE table (Initial Concentration, Change in Concentration, Equilibrium Concentration) and the quadratic formula unless the "x is small" approximation can be used.
What is the possible chemical explanation for this? I understand that a reaction using a thiamine catalyst at room temperature for 48 hours may lead to lower yield due to catalyst decomposition, but I'd like to know a more technical explanation.
calculate the molarity of a solution made by adding 12.9 of CaCl_2 to a flask and dissolving the solid to total volume of solution equal
