When an ion-selective electrode for X was immersed in 0.0670 M XCl, the measured potential was 0.0250 V. What is the concentration of X when the potential is 0.0400 V
The temperature of the calorimeter and the 1 kg of water rose from 20.45 degrees Celsius to 23.65 degrees Celsius. The heat capacity of the calorimeter is 2.21 kJ/Degrees Celsius. Using this information, determine the heat of combustion per mole o..
The data obtained are 20.36, 19.98, 20.26, 20.18, 19.72, 19.86% Cl. (a) what is the standard deviation of this data. (b) find the 90% and 99% confidence intervals for the percentage of chloride in the sample. Must show work for credit
If a 2.1 L reaction vessel initially contains 723 torr of cyclopropane at 485 degrees C , how long will it take for the partial pressure of cylclopropane to drop to below 105 torr ?
Write equations for the half-reactions that occur in the electrolysis of molten potassium bromide.
Because the potential of pH electrodes can vary, it is necessary to CALIBRATE a pH electrode before use. For many uses, a two-point calibration procedure is appropriate.
An unknown mass of each of the given substances as with The final temperature is recorded as indicated 1.Pyrex glass (tf=67.6 C), 2.Sand (tf=70.4 C), 3.ethanol (tf=45.9 C), initially at 19.0 degrees celsius, absorbs 1930 Joules of heat
