This chemistry video tutorial focuses on conceptual problems relating to le chatelier's principle and ksp - the solubility product constant. It explains how to determine the direction in which the reaction will shift if the concentration of the product ions changes. It also explains how to determine if precipitation or dissolution will occur due to changes in concentration or temperature for an endothermic reaction and how to determine the effect of pH on the molar solubility of a compound. This video also explains how to determine which compound will have the highest molar solubility given the ksp values.

This chemistry video tutorial explains how to calculate the enthalpy of reaction by using the average bond dissociation energies listed in a table. It contains examples and practice problems of calculating the enthalpy of formation of 1 mole of HCl, the enthalpy of combustion of methane and the enthalpy of reaction between methane and chlorine. The enthalpy of reaction is equal to the sum of all the bond energies of the reactant minus the sum of all the bond energies of the products. Breaking a bond is an endothermic process while forming a bond is an exothermic process.

This chemistry video tutorial explains how to calculate the height of water in a barometer given the density and column height of a mercury barometer. This tutorial explains how to derive the formula to calculate the column height of water using other equations in physics and geometry. The weight of the atmosphere must equal the weight of the fluid in the column for equilibrium to be established. Knowing this, you can derive the formula using density and the volume of a cylindrical prism.

This calculus video tutorial explains how to find the limit at infinity. It covers polynomial functions and rational functions. The limit approaches zero if the function is heavy at the bottom or if the degree of the denominator exceeds that of the numerator. The limit approaches a constant value if the degree of the numerator and the denominator is the same. If the numerator has a higher degree, the limit will approach positive or negative infinity.
