Hello,
I am doing a lab currently where we are required to find the Molar Heat in kJ / mol of salt dissolved of the salt, NH4Cl
To start the experiment, I dissolved the salt into an amount of water (values below) and recorded temperature changes.
Mass of NH4Cl = .9 g
Mass of H2O =...
Thanks
No he has not mentioned filler, is that something I should research?
I think what your saying is backward from what I need to find. I am supposed to find the CO[SIZE="2"]2 volume theoretically using just the values of H[SIZE="2"]2O and Alka-Seltzer in grams.
If I am understanding...
Thanks
Thanks, I got the right answer for the experimental (or atleast I was within my professor's percent error). Now, I have to find a percent yeild, or the percent I was off by the theoretical. I do not understand how to perform the stoichiometry for the equation he gave us today.
The...
Correct. TO make the experiment clearer, here is another instruction set.
I took one sealable bag and weighed it. I placed exactly 30 mL of water inside the bag. I dropped 1g of Alka-Seltzer in the water after the bag was sealed. I weighed the bag with the gas, products still inside. I...
Ok, I believe I have found an equation that shows what is happening. I am not 100% positive that this is the correct equation:
3HCO[SIZE="1"]3 (-1 charge)(aq) + H[SIZE="1"]3C[SIZE="1"]6H[SIZE="1"]5O[SIZE="1"]7 (aq) ----> 3CO[SIZE="1"]2 (g) + 3H[SIZE="1"]2O +...
I'm not sure, I haven't found a clear answer on the web either, all of the sites I pull up will tell me that it has aspirin sodium bicarbonate (baking soda) and citric acid. Knowing what the full equation is would really help if anyone knew it. Still, I cannot figure out a way to find the...
Finding Amount of CO2 Help Please
I am having trouble with my Alka-Seltzer, Water lab.
The purpose of the lab is to figure out how much CO[SIZE="1"]2 is produced when an amount of Alka-Seltzer is mixed with an amount of water. The only equation we have is:
Alka-Seltzer + H[SIZE="1"]2O...
