Oxygen and sulfur combine to form a variety of different sulfur oxides. some are stable molecules and some, including S2O2 and S2O3, decompose when they are heated. draw lewis structures for these two compounds showing all resonance forms. draw all resonance forms but do not add double headed arrows
What are the missing coefficients for the skeleton equation below?
A plot of ln[AV] versus t (s) gives a straight line with a slope of -0.32s^-1. What is the value of the rate constant (k) for this reaction?
we are doing an analysis of cola lab in my chem I lab. We have to do pre-lab questions and one of them is- how will you use compounds of different colors to determine the relationship between percet transmittance and wavelength? or between absorba..
Explain the following observations. 1. Aziridines, compounds that contain nitrogen in a three-membered ring, undergo pyramidal inversion much more slowly than do other alkylamines
At 25 ºC, the vapor pressure of water is 23.8 torr. What is the vapor pressure of a solution prepared by dissolving 97.0 g of C6H12O6 (a nonvolatile solute) in 170 g of water.
An individual's blood alcohol content (% alcohol in blood as measured mass per volume = mass of alcohol per volume of blood) was 0.15. If we assume the individual drank all of the alcohol at once
Write a balanced equation for the reaction. What volume of 0.200M MnO4- solution is needed to titrate 22.5mL of a 0.350M solution of ethanol?
