Why does the temperature of a solution increase if the reaction is exothermic? For example, in the precipitation of silver iodide, delta H is -110.7 kj. Why is this reaction exothermic and why does it cause the solution temperature to increase?
in the process three evaporators are used in series to reduce the water level of an incoming brine solution which
the combustion of ethane produces carbon dioxide and steam2c2h6 7o2 --- 4co2 6h20how many moles of co2 are produces
What is the number of moles of atoms of oxygen contained in 49 grams of sulfuric acid, H2SO4?
an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green, the pH is 3.95. The final color of the solution is dark blue.
Whereas B has been determined to be the kinetic product, C has been determined to be the thermodynamic product. Complete potential energy diagrams for the formation of B and C by sketching the energy curve for each product.
Concentration of glucose complex form stock? Set of standard solns was prepared by taking a known volume of a stock glucose soln, containg 1.000 g glucose dissolved in 100 mL of distilled water
At what temperature would a 1.80 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 degrees C/m. answer in degrees C
Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered 1.500L of solution. What was the concentration in ppm of silver ions in the original solution?
Although an optical rotation of +123° can also be read as -237°, is a specific rotation [a] of +123° the same as one of -237°. If you measured an apparent rotation a of +123°, how could you determine whether or not it is really -237°
25.00 mL of 0.1000 M chlorous acid, HOCl = O is titrated with 0.1000 M NaOH. Calculate the pH of the solutions when 0.00, 2.00 and 24.00 mL of the titrant was added.
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted
