The purpose of the lab was to determine the equation for the decomposition of sodium bicarbonate. endobj <> one reaction actually occurs. The balanced equation for this chemical reaction is. The two possible equations were: I understand that the correct equation is supposed to be the first one where sodium carbonate was produced. As the temperature of 5. Your data supports the hypothesis that the sodium bicarbonate decomposed to sodium oxide. Record the Unknown sample number you are planning to analyze. The lab procedure that my class used can be found in the photo attachment. WebDue to the widespread use of sodium bicarbonate (commonly called baking soda) in many food products, the thermal decomposition reaction has been studied extensively by food chemists. Do these numbers support your conclusion about which reaction is really occurring? Neither Achieve nor the lead states and partners that developed the Next Generation Science Standards were involved in the production of this product, and do not endorse it. it wouldve affected your percent yield. endstream WebWhen a chemical substance decomposes it breaks down to form two or more separate compounds. You can track the progress and be sure your project is gonna be ready on time. I am reviewing a very bad paper - do I have to be nice? Let the test tube cool for about 10 minutes.
