For the process of melting ice, DeltaH = 1.44kcal/mole, and DeltaS = 5.26 cal/mole K. From this data, calculate the temperature at which ice is in equilibrium with liquid water.
Which of the following is a correct neutralization reaction?
Calculate the equilibrium concentrations if the initial concentrations are 2.31M N2 and 0.54M O2. (This N2/O2 concentration ratio is the ratio found in air.)
An automobile gasoline tank holds 35 kg of gasoline. When the gasoline burns, 88 kg of oxygen is consumed, and carbon dioxide and water are produced.
