The flask shown here contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.300 M NaOH. A. What volume of NaOH is needed to reach the end point of the titration?
What is the minimum amount of energy from the sun required to produce 4 g of glucose in this way? ?Hf of glucose is -1260 kJ/mol.
Because the potential of pH electrodes can vary, it is necessary to CALIBRATE a pH electrode before use. For many uses, a two-point calibration procedure is appropriate.
the electric potential energy associated with an electron and a proton is -4.35*10^-18 j. what is the distance between these two charges?
Calculate the sulfur hexafluoride partial pressure when a circuit breaker with this gas mixture reaches its rated limit of -40.0 degree celcius. How does the density of the gas in the circuit breaker change as the temperature drops
The greater volume per mole at the higher temperature indicates greater average intermolecular distances and hence weaker intermolecular forces.
