You have a 550 mL tank of gas with a pressure of 1.56 atm at 24.0°C. You thought the gas was pure carbon monoxide but later found it was contaminated by small quantities of gaseous CO2 and O2. Analysis shows that the tank pressure is 1.34 atm (at 24.0°C) if the CO2 is removed. Another experiment shows that 0.0870 g of O2 can be removed chemically. What are the masses of CO and CO2 in the tank?
After tert-amyl chlorid has been distilled, one notices that there is some liquid remaining and this liquid distills at approximately 373.15K.
A stellar object is emitting radiation at 3.75 mm. If the detector is capturing 3.3*10^8 protons per second at this wavelength, what is the total energy of the photons detected in one hour
Given that the sample is a mixture of multiple chemicals and you are NOT given a mixture of KNOWN quantities, what experiement(s) should we do to create our own KNOWN data
Calcium Hydroxide is a strong electrolyte. Determine the concentration of each of the individual ions in a 0.30 M Ca (OH)2 aq solution.
A 100. mL sample of 0.200 M aqueous hydrochloric acid is added to 100. mL of 0.200 M aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 480. J/K. The following reaction occurs when the two solutions are mixed.
