In a constant-pressure calorimeter, 60.0 mL of 0.930 M H2SO4 was added to 60.0 mL of 0.290 M NaOH. The reaction caused the temperature of the solution to rise from 24.28 °C to 26.26 °C. If the solution has the same density and specific heat as water, what is ?H for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
Use the observations and arrange the following five reduction half-cell reactions in order, the one with the largest positive reduction potential listed first.
Oxidation of A with KMnO4 gives CO2 and the keto carboxylic acid D shown below. Propose a structure for A.
when carbon is burned in the presence of oxygen, the carbon and oxygen combine to produce carbon dioxide. if you start with 3 grams of carbon and 8 grams of oxygen and they react completely, how many grams of carbon dioxide will be produced?
A balloon filled with 5.00 L of He is under 3.00 atm of pressure at 315 K. What will happen to the volume of the gas if the temperature drops to 255 K and the pressure changes to 1.50 atm.
