Calculate the weight of calcium calcium carbonate required to produce carbondioxide that is sufficient for conversion of one decimole sodium carbonate to sodium bicarbonate. |
|
Answer» Solution :Step 1: Regarding the requirement of cabon dioxide: The balanced equation for conversion of sodium carbonate to sodium bicarbonte is `Na_(2)CO_(3)+H_(2)O+CO_(2) to 2NaHCO_(3)` Decimole =0.1 mole 1mole of `Na_(2)CO_(3)="1 mole of "CO_(2)` Carbondioxide required for 0.1 mole of `Na_(2)CO_(3)=` 0.1 mole (or 4.4 grams) Step 2: Regarding the requirement of CALCIUM carbonate. The balanced equaiton for the decomposition of calcium carbonate is `CaCO_(3) to CaO+CO_(2)` 1 mole of `CO_(2)="1 moleof "CaCO_(3)` 14 grams of `CO_(2_)="100 grams of CaCO_(3)` The weight of calcium carbonate to produce the required 4.4 grams carbondioxide `=(100)/(44) xx4.4 =10"gramas"` |
