Calculate the de Broglie wavelength in meters of a neon atom with a mass of 3.35 × 10(-26) kg that has a speed of 2.32 × 106 m/s. Express answer in scientific notation.
The empirical formula is NO2. If the molar mass is 92g/mol give the molecular formula.
The conversion of sulfur dioxide into sulfur trioxide with oxygen gas must be closely monitored during the manufacture of sulfuric acid. The Kc = 1.7 x 104 at exactly 600K. If PSO3 = 300atm and PO2 = 100atm, calculate PSO2 and Kp.
