Please can someone answer this it would be a life saver
In this experiment, you will identify an unknown as either sodium carbonate ("soda") or sodium hydrogen carbonate (sodium bicarbonate or "baking soda"). The method will involve the reaction of the unknown with excess hydrochloric acid, which will occur according to one of the two following reactions: Na_2C0_3(aq) + 2HCl(aq) right arrow 2NaCl(aq) + C0_2(g) + H_20(l) NaHC0_3(aq) + HCl(aq) right NaCl(aq) + C0_2(g) + H_20(l) Both reactions produce the same products, but not in the same proportions. Thus, gravimetric analysis of the solid product, NaCl, can be used to determine the identity of the unknown. Calculate the predicted yield (in g) of NaCl assuming your unknown is sodium carbonate. the predicted yield of NaCl (in g) assuming your unknown is sodium hydrogen carbonate. What is the most probable identity of your unknown Explain. Suppose your unknown had been a hydrated form of sodium hydrogen carbonate with the formula NaHC0_3-H_20. What would differ in your calculations Could you still have distinguished it from sodium carbonate Explain.Explanation / Answer
