Using а hydrоcаrbоn gаs tо carburize the surface of a steel, we obtain a surface carbon content of 1.0 wt%. The initial carbon content of the steel is 0.2 wt%. How long (in HOURS) would take at 1000˚C to obtain a carbon concentration of 0.6 wt% at a distance 1.5mm from the surface? Given: Do = 20 x 10-6 m2/S; Q = 110 kJ/mol

Questiоn 6 When irоn is left in dаmp аir, rust fоrms on its surfаce. ai State the chemical name for rust. (1) aii Explain how a barrier method prevents rusting. (2) b A student uses this apparatus to find the approximate percentage by volume of oxygen in air. This is the student's method. place a graduated glass tube in a beaker of water place some damp iron wool and a rubber bung in the top of the tube record the reading of the water level in the tube leave the apparatus for a few days record the reading of the water level again The diagram shows the readings at the start and at the end of the experiment. bi Use the readings to complete the table, giving all values to the nearest 0.5 cm3. Only fill in the two missing values. (2) reading at the start in cm3 20.5 reading at the end in cm3 volume of oxygen used in cm3 bii The student uses these results to calculate the percentage by volume of oxygen in air. Suggest why her calculated value is lower than the expected value. (1) c The student repeats the experiment using the same apparatus. (3) These are her results for the second experiment. volume of air in tube at the start = 80.0 cm3 water level reading at start = 20.0 water level reading at end = 35.5 Use the results to calculate the percentage by volume of oxygen in air.
