Problem: Sulphur (IV) oxide reacts with oxygen to form sulphur (VI) oxide.
Required:
Question 1: Explain why we can't assume that the pressure and the temperature of both gases will remain the same during the entire reaction.
Question 2: Calculate the volume of oxygen required to react completely with 75 L of sulphur (IV) oxide.
Question 3: Calculate the volume of sulphur (VI) oxide produced.
A very crude model of the buckminsterfullerene molecule (C60) is to treat it as a collection of electrons in a cube with sides of length equal to the mean diameter of the molecule (0.7nm)
Using the Bohr formula for the radius of an electron orbit, estimate the average distance from the nucleus for an electron in the innermost (n = 1) orbit of a cesium atom (Z = 55). (in m)
Calculate the percentage of monochlorinated products anticipated in the monochlorination of 2,4-dimethylpentane.
A 22.0 L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.0 atm. Enough weight is suddenly removed from the piston to lower the external pressure to 1.5 atm. The gas then expands at constant temperature until its pressure i..
