If potassium ion is in solution, the ion could be reduced to potassium metal. In acidic solution, which would be more thermodynamically favorable: the reduction of K+ or the reduction of H+
What is the pressure (in millimeters of mercury) inside a container of gas connected to a mercury-filled open-end manometer of the sort shown when the level in the arm connected to the container is 17.2 cm lower than the level in the arm
The selenite ion is an oxoanion of selenium bearing a negative two charge and containing three oxygen atoms. Write the formula for the selenite ion.
Consider the reaction 2ZnS + 3O2 → 2ZnO + 2SO2. Suppose that you wanted enough O2 to completely react with 500. g of ZnS. What mass of O2 should be present?
How can their efficiency be less than 100% and the Law of Conservation of Energy still be valid? An incandescent light bulb functions because of the flow of electric current. Does the incandescent light bulb convert all of the electrical energy to..
If the charge calculated in the first part of this question is passed through a cell constructed of copper electrodes immersed in an acidic solution of copper sulfate (0.5 M CuSO4/0.1 M H2SO4), what mass of copper, in mg, will be deposited on the ..
Carboxylic acids have higher than expected boiling points due to dimeric associations involving hydrogen bonding. The structure of 3-methylbutyric acid is shown below. Draw a second molecule of 3-methylbutyric acid
