Essay On Stoichiometry

Background : Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. In the lab that I did with my group we used stoichiometry to find out the decomposition of sodium biocarbonate. Sodium carbonate is just another name for baking soda, and that is what we used on our lab. Baking soda is also used in some food items, such as pancakes, waffles etc… When the baking soda is being heated the decompositon part occurrs and when this happens it releases gas and the baking soda’s texture changes.

In the lab experiment my group and I were conducting to see the outcome of baking soda after it has been heated. It is heated at a certian temperature, usually pretty high so that there can be a transformation in the baking soda. Something else that was a key factor to this experiment was the stoich work behind all the measurments and weights of all the components. Without the stoich equations it would not be able to accomplish this experiment. Stoichiometry is a very helpful way to discover what …show more content…
The second stoich equation which is NaHCO3 → Na2CO3 (s) + CO2(g) + H2O(g). After balancing the equation my product was 2NaHCO3 → 1Na2CO3 (s) + 1CO2(g) + 1H2O(g). The reason I had chosen this answer was because the grams of baking soda that I had begun with was the closest to the answer of this stoich problem according to the information and work I had done. The final answer after doing the stoich problem that I had come up with was 3.78gNa2CO3. My beginning weight of the baking soda was 6 grams. Also the Carbon dioxide is being released while the baking soda was being heated, therefore the grams and weight of the element was evening out to somewhere apporximately near the number of grams, my group had started with in the beginning of the
