A disproportionation reaction is one in which identical species react. Balance this redox reaction for this self-reaction of nitrogen dioxide in acidic solution to form nitrogen compounds of both lower and higher oxidation states. Provide the sum of the coefficients in the balanced equation. NO2 (g) → NO3– (aq) + NO

The density of an unknown gas at 98°c and 740 mmhg is 2.50 g/l. what is the molar mass of the gas with work showed?

Identify the electromagnets with poles that are reversed from the electromagnet shown above

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
