10. nitrous oxide (n2o) can be obtained by the thermal decomposition of ammonium nitrate (nh4no3). (a) write a balanced equation for the reaction. (b) in a certain experiment, a student obtains 0.340 l of the gas at 718 mmhg and 24°c. if the gas weighs 0.580 g, calculate the value of the gas constant.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
