A salt bridge is used in voltaic cells to balance the ions and complete the circuit. Describe this scenario. (hint;use a diagram)
Consider the hypothetical reaction A 2B, for which ?Go is -16.6 kJ/mol. In a certain experiment, the initial concentrations are [A] = 8.00×10-3 M and [B] = 2.500 M at a temperature of 298 K. Calculate G for the reaction at these concentrations.
Which species is amphoteric. 1) HNO3(aq) 2) Cl-(g) 3) CO32-(aq) 4) HSO3-(aq) 5) PO43-(aq)
an environmental chemist needs a carbonate buffer of ph 10.00 to study the effects of acid rain on limestonerich soils.
A compound containing xenon and fluorine was prepared by shinning sunlight on a mixture of X2 (0.526 g) and excess F2 gas. If you isolate 0.678 g of the new compound, what is the empirical formula
You then remove 24.9 mL of this solution and dilute it to 656.0 mL to create Solution B. You then determine that Solution B has a molarity of 0.00042. What was the concentration of Solution A
Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. A solution containing 3.30 g of sodium carbonate is mixed with one containing 4.71 of silver nitrate.
While a piece of metal is irradiated with UV radiation, electrons are ejected with a kinetic energy of 5.96 x 10-19 J. Explain what is the work function of the metal
Draw additional molecules of sulfanilamide and hypothesize the intermolecular interactions that are most important for providing a stable and selective crystal structure
Write a balanced equation for the reaction that occurs when hydrogen sulfate ion behaves as a Brønsted-Lowry acid in water.
Problem- In 2011, researchers showed that hypochlorous acid (HClO) generated by white blood cells kills bacteria. Calculate (Ka)=2.9X10^-8 the percent dissociation of :( A). 0.40 M HClO, (B) 0.035 M HClO
A 0.4600 g sample of carboxylic acid is burned in oxygen, producing 0.8202 g of CO2 and 0.3377 g of H20. Determine the empirical formula of the carboxylic acid.
The solution was prepared by dissolving 0.0005 mol of Ba(OH)2 in 100 ml of solution.If the base is assumed to ionize completely,the pOH of the solution will be.?
