If an iron ore contains FeCO3, Na2CO3 and FeS2, what kind of reactions may form during roasting ? Write their equations.?
THE CHECK ENG. LAMP ON MOST LATE MODEL VEHICLES WILL ILLUMINATE PRIMARILY WHEN THERE IS A CONDITION WITHIN THE POWER TRAIN COMPUTER CONTROL SYSTEM THAT IS MALFUNCTIONING. THE PROBLEM CAN BE A FAILED COMPONENT AND/OR A CONDITION THAT IS BEYOND THE CONTROL SYSTEMS ABILITY TO CONTROL. THERE ARE NUMEROUS DIAGNOSTIC TOOLS ON THE MARKET (SCANNERS) MANUFACTURED , THEY PRIMARILY CONNECT TO SYSTEM VIA A DATA LINK CONNECTOR (MOST LATE MODEL VEHICLES ARE OBDII COMPLIANT) AND ONE CAN READ A ALPHA NUMERIC CODE THAT IS STORED IN THE SYSTEMS MEMORY WHICH WILL LEAD THE TECHNICIAN TO THE AREA OF CONCERN, THE ELECTRONIC CONTROL SYSTEM OF THE MODERN VEHICLE IS A COMPLEX SYSTEM. SIMPLY REPLACING A COMPONENT THAT A DIAG. CODE POINTS TO MAY NOT ALWAYS CORRECT THE PROBLEM. CONDITIONS CAN ARISE THAT CAN CAUSE THE C.E.LAMP TO ILLUMINATE, (SUCH AS VACUUM LEAKS, LOOSE FUEL CAPS, UNPLUGGED SENSORS FROM AIR CLEANER HOUSINGS, AND SO ON). NUMEROUS PARTS STORES CAN PLUG IN AND READ THE TROUBLE CODE WHICH MAY BE OF SOME HELP. ALSO IF YOU'RE FAMILIAR W/ YOUR UNDER-HOOD TAKE A VISUAL , YOU MAY NOTICE SOMETHING UNPLUGGED OR DISCONNECTED (THE CODE WILL BE OF HELP). IT MAY BE NECESSARY TO HAVE IT DIAGNOSED AND REPAIRED BY A TRAINED VEHICLE REPAIR TECHNICIAN. IN ADDITION THE CODE AND LAMP WILL HAVE TO BE CLEARED UPON COMPLETION OF THE REPAIR W/ A SCANNER OTHERWISE THE SYSTEM WILL NOT RESET. HOPE THIS HELPS LOU , ASE CERT. MASTER AUTO TECH. ASE CERT.

Check the tightness of the gascap. A loose cap will set off the check engine light.
Buy an OBDII scanner from the auto parts store for $70. You'll be able to read the codes from any car built since 97. You can plug it into your friends cars when they get a light and look like a mechanical genius. A lot of time a certain combination of pressure and temperature reading make the light come on and it never happens again.
4 FeCO3 + O2 → 2 Fe2O3 + 4 CO2 Na2CO3 → Na2O + CO2 4 FeS2 + 11 O2 → 2 Fe2O3 + 8 SO2 or 3 FeS2 + 8 O2 → Fe3O4 + 6 SO2 depending on conditions
