The decomposition of N2O5 (g) at 67 °C has a rate constant of 5.80×10⁻³ s⁻¹. 2N2O5 (g) → 4NO2 (g) + O2 (g) A sample of pure N2O5 (g) at a pressure of 4.68 atm undergoes decomposition for 145 seconds. Determine the total pressure within the reaction container at this point. Assume constant volume and temperature.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
