Calculate the equilibrium concentrations of , , and in a reaction mixture obtained by heating 5.65 of steam and an excess of solid carbon in a 5.45 container.
Explain how the vapor pressure of a compound is related to the liquid-vapor equilibrium and its equilibrium constant.How would it vary with the addition of more liquid?
The Aldol condensation is very sensitive to the mole of ratio of starting materials used. What would be the products of 1:1 mole ratio
Calculate the number of molecules of AsCl3 that would be in 1 mL of Solution C at this concentration. Look at your answer. This is the average number per mL. But what is the most likely number (ie integer) of molecules of AsCl3 in 1 mL?
H2O is amphoteric meaning it can act as both a Bronsted acid and a Bronsted base.Show that H2O really is amphoteric by writing the relevant equations
A sample containing 0.187 g Cl- is dissolved in 50.0 mL water. How many moles of Cl- ion are in the solution? What is the molarity of Cl- ion in the solution?
