How many moles of NaBrO should be added to 1.00 L of .050 M hypobromous acid (HBrO) to form a buffer solution of pH 9.15. Assume o volume change occurs when the NaBrO is added.
How many liters of water vapor can be formed by the reaction of 275.0 liters of oxygen gas and 250.0 grams of pentane? Which reactant is limiting? How many grams of the excess reactant are left over?
If the reaction is allowed to proceed until all substances have reached their equilibrium concentrations, determine delta G for the reaction.
Microwave ovens heat food by creating microwave electromagnetic radiation that is absorbed by water molecules in the food. Any material that does not have water in it will not absorb the radiation and will not get hot.
