Decide whether or not a reaction will occur when a solution of Cadmium(II) Chloride is treated with nitric acid HNO3(aq). Write a balanced equation for any reaction that occurs.
Describe how you prepare 5.00 times 10^2 mL of 0.7 M CuSO4. How many grams of CuSO4 are needed. How many significant figures are used for the mass. What type of container should it be made up in.
What is the molarity (M) of the concentrated HClO4 solution?
Acetylene, C2H2, is a gas commonly used in welding. It is formed in the reaction of calcium carbide, CaC2, with water. Given the thermochemical equations, calculate the value of ?H°f for acetylene in units of kilojoules per mole.
This indicates that the solution is now more acidic, and the reaction shifts to the right, working to lower the concentration of hydrogen ions, and return to equilibrium
How many moles of water are produced in this reaction?
