Question

Hey guys. I need help answering these questions:
(Lab Procedure shown below)
Write the complete balanced equation for the reaction that occurred in this lab. Hint: H2CO3 is not a final product of the double-replacement reaction; it breaks down (decomposes) immediately into two products.

The NaHCO3 is the limiting reactant and the HCl is the excess reactant in this experiment. Determine the theoretical yield of the NaCl product, showing all of your work in the space below.

Determine the percent yield of NaCl in your experiment, showing all work neatly in the space below.

Answer 1

If you had not heated the product long enough to remove all of the water, explain in detail how that would have specifically affected your calculated actual yield and percent yield.

Answer 2

I know most of you will say "we didn't do the lab". But, I have the lab procedure.

Measure the mass of a clean, empty evaporating dish and record it in the data table (24.35 g).
Place three or four scoops of solid NaHCO3 in the evaporating dish.
Measure the mass of the dish and NaHCO3 and record it in the data table (37.0 g).
Slowly add the HCl, drop by drop, to the dish with the NaHCO3. Keep adding drops of HCl until bubbles no longer form. Add 3 more drops to make sure you have added an excess of the HCl and that the reaction is complete (40.6g)
Set the dish on the wire gauze above the Bunsen burner and gently heat to evaporate the water, leaving behind the salt produced by the reaction.
Heat the mixture until it appears dry and you cannot hear any sizzling. It is better to heat the mixture too long than not long enough.
When you think all the water has evaporated, turn off the burner and allow the dish to cool.
Measure the mass of the dish and the salt product (31.52 g).
Rinse the dish into the sink.

Answer 3

Hold on, let me do this lab for you when I go to my lab later today!

Answer 4

Thanks :)

Answer 5

Are you joking? I'm not going to do your work for you! This is \(your\) lab experiment!

Answer 6

I tried it but I don't understand it. At this point, the only thing I need help with is finding the theoretical yield.
