What is the concentration (in M) of the chloride ion when 18.2 mL of a 0.503 M solution of sodium chloride is combined with 18.9 mL of a 0.504 M solution of iron(III) chloride? Assume the volumes are additive.
Calculate the solubility (in grams per 1.00*10^2 mL) of magnesium hydroxide in a solution buffered at pH=10. How does this compare to the solubility of Mg(OH)2 in pure water
The rate at which a metal alloy oxidizes in an oxygen containing atmoshphere is a type of the Arrhenius equation (rate(k)=Ce^(-Q/RT)). For example, the rate og oxidation of
