Nitrous oxide (N2O) is used as an anesthetic (laughing gas) and in aerosol cans to produce whipped cream. It is also a potent greenhouse gas. The decomposition of N2O is first order. It decomposes slowly to N2 and O2: How many half-lives will it take for the concentration of the N2O to reach 25.00 % of its original concentration?

Nitrous oxide (N2O) behaves as an ideal gas and has a heat capacity at constant pressure CP = 38.6 J/K∙mol. 4.2 moles of N2O initially at 298 K are heated at constant pressure until a final temperature of 358 K is reached. (a) Calculate the enthalpy change of N2O during that process. (b) Calculate the heat transfer Q during that process. (c) Calculate the work W performed during that process. (d) Calculate the change in internal energy ΔU during that...

According to a report* published in 1990 in the journal Anesthesia Progress, breathing nitrous oxide (N2O) causes “happy, euphoric mood changes ... and experiences of a dreamy, detached reverie state.” The concentration used in the study was XN2O = 0.3. Our classroom is 3 m x 6 m x 6 m. If I bring a 5 lb (2.25 kg) tank of N2O to class, will it provide enough gas to induce euphoria? (you can estimate the temperature and pressure on...

The decomposition of nitrous oxide at 565 °C N2O(g)----> N2(g) + ½ O2(g) is second order in N2O. In one experiment, when the initial concentration of N2O was 0.790 M, the concentration of N2O dropped to 0.103 M after 5.21×10^3 seconds had passed. Based on these data, the rate constant for the reaction is _____________ M-1 s-1.
