1.	aluminium carbide contains 75% of Al,aluminium oxide contains 52.9% of Al & carbon dioxide contains 27.27% of C.show that these figures illustrate the law of reciprocal proportion
Answer» m carbide contains 75% of AL and 25% of C. So 3 grams of Al combines with 1 gram of C. Or, ratio Al : C = 3 : 1Aluminum oxide contains 52.9% of Al and 47.1% of Oxygen. So ratio Al : O = 52.9 : 47.1 = 1.123 : 1 or, 3 : 2.671 Carbon dioxide contains 27.27 % of C and 72.73% of O. So ratio C : O = 27.27 : 72.73 or , 1 : 2.667 or nearly equal to 2.671 above.So carbon and Oxygen combine in the same ratio as they REACTED with ALUMINUM.
