When 28.0 ml of 0.500 M H2SO4 is added to 28.0 ml of 1.00 M KOH in a coffee-cup calorimeter at 23.50 degrees Celsius, the temperature rises to 30.17 degrees Celsius. Calculate the delta H of this reaction.
Galvanic cell consists from CO/CO2+ standard electr0de and NI/NI2+ ELECTRODE. At what concentration of nicle electrolyte the theoretical
What is the final temperature when 150 mL of water at 90,0 C is added to 100.0 mL of water
a) The nitric oxide molecule, NO, readily loses one electron to form the NO+ ion. Why is this consistent with the electronic structure of NO. Predict the order of the N--O bond strengths in NO, NO+, and NO-, and describe the magnetic properties of e..
