in a compound carbon and oxygen react in ratio of 3 is to 8 by mass to form carbon dioxide what mass of oxygen is required to react completely with 9 gram of carbon |
|
Answer» tion:Carbon and oxygen combine together to FORM co2 The ratio of their COMBINATION is 3:8 Now, Let the MASS be x So, The ratio of the combination will be 3x: 8x Now, Mass of oxygen is given as 32 GRAMS So, 8x = 32 Or, x = 32/8 = 4 grams So, The mass of carbon to react with 32 grams of oxygen is 3x So, 3x = 3*4 Or, 3x = 12 grams Therefore, 12 grams of carbon will react completely with 32 grams of oxygen. |
