The balanced equation for There are three theoretically possible chemical reactions that could occur during the thermal decomposition of baking soda. WebStoichiometry Lab Report Introduction: (Jack) The law of conservation of mass and the law of definite proportions are correctly explained by John Dalton with the use of his atomic theory. This would have yielded an answer similar to the one you got. I have been using study bay for nearly two years now and my writer HaroldCH has provided top star quality. The decomposition reaction of sodium bicarbonate or baking soda is an important chemical reaction for baking because it helps baked goods rise. From the mass of the solid product ("residue"),studentsshould be able to decide if it is Na2CO3or Na2O. Thanks for contributing an answer to Chemistry Stack Exchange! 2. Allow the crucible to cool in the clay triangle. maybe the OP could also study the calculations to find the error.
