(b) the decomposition of solid calcium hydroxide into solid calcium(II) oxide (lime) and water vapor;
(c) the combination reaction between nickel metal and chlorine gas.
The solubility of CO2 in water at 25C at 1 atm is 0.034mol/L. What is the mass of CO2 found in a 355 ml can of soda at 25 C, assuming the manufacturer used a pressure of 2.O atm of CO2 to carbonate the beverage.
Problem- What is the relative stability of alpha and beta-d-glucose pentaacetate? How can you account for the product mixtures that form under conditions of acidic and basic catalysis in the synthesis of Alfa and beta D-glucose pentaacetate
The equilibrium lies far to the right. The reaction will proceed very slowly. The reaction contains significant amounts of products and reactants at equilibrium. The equilibrium lies far to the left.

How many moles of O2 are required to completely react with 1.77 moles of C3H6 according to the following reaction. 2CEH6 + 9O2 => 6CO2 + 6H20
Draw the structures of both deprotonated isomers and explain how the difference in cis and trans arrangements allow the single-deprotonated form of maleic acid to form a hydrogen bond with itself but fumaric acid cannot form a similar hydrogen bon..
In the above scenario, t he surrounding performed 20KJ of work on the system. How much heat would the system have to have gained or lost in order for the internal energy of the system to have remained constant throughout the process. You must show al..
Calorimetry is a method used to measure changes in enthalpy, or heat, that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
