My assignment is asking;
(a) Use a potential energy diagram to describe the chemical change and the energy change in an electrolytic cell containing materials of your choice.
(b) Describe how the minimum voltage for the cell you have described relates to the changes in potential energy shown on this diagram
a sample of 5.00 g of methane occupies 14.5 dm3 at 310k. calculate a the work done when the gas expands isothermally
A buffer solution of pH of 9.25 contains P mol of a weak base and Q mol of a salt of its conjugate acid. When 120 cm3 of a 0.0140 mol.dm-3 solution of hydrochloric acid was added to this buffer solution
Question- You needs to produce a buffer solution that has a pH of 5.26. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this..
After equilibrium was established, which of the ions listed below was present in the greatest concentration?A) H2C6H5O7^-
Given that you know one gas in a mixture of gases has a pressure of .5 atm, and has a mol fraction of .18, what volume will the mixture of gases occupy if the temperature is 390 kelvin, the total number of moles of all the gases combined are 20?
SLIGHTLY LESS than 100 degrees Celsius, but the final boiling point was AT 100 degrees Celsius. Why should the boiling point rise as the distillation progresses?
The pressure of the gas as well as the atmosphere is equalized, utilizing the method described in this experiment. The atmospheric pressure is 738 mmHg. The temperature of the water as well as that of the gas is identical at 26 Celsius. Explain ho..
In naming disubstituted benzenes, "1,2" substitution is also known as: A. meta substitution. B. para substitution. C. ortho substitution. D. isomer substitution. E. none of the above
What is the overall balanced reaction in the direction that it is spontaneous and calculate the standard cell potential.
A sample consisting of 3.0 mol of ideal gas molecules at 200K at 2.00 atm is compressed reversibly and adiabatically until the temperature reaches 250K.
