Hi I just completed a lab called determination of sodium
carbonate and I need to calculate and report the percentage of
Na2CO3 in the unknown sample as well as the standard. I also need
to find the experimental mean, standard deviation, RSD, and 95% CI.
Can you explain to me how you do it? Thank you!

Hi, I just did a Lab experiment called the Air Bag Experiment which involved sodium bicarbonate and sulfuric acid. The first experiment with the selected bag had sodium bicarbonate as the limiting reagent and the second experiment with the same bag had sulfuric acid as the limiting reagent both of these conditions will cause for the bag to inflate. I was giving a discussion question that asked: Why would the bag inflate the same for each condition?

Hi I need help plotting this graph from my thin lenses lab. They want me to pick two sets of points from my data. The first set will become p1 and q1 and the second set will become p2 and q2. Plot q1 and p1, and q2 and p2 on the same graph. (Hint: select values of p1 and p2 such that the difference between them is at least 30cm.) I'm using this to find the the intersection of the...

I need help finding how to do the calculations for these
tables. If you could show me how to do the 1st determination/ trial
1 for each of them, I can figure out how to do the second and third
determinations/trials. If you could also show me how to do the
standard deviations, that'd be much appreciated. Thank you!

I need to identify the unknown structure.
Please help me identify the importance of each peak in the

What would the reactions look like for this structure when it
reacts with ethanol for DNPH test, CrO3 and dioxane and NaOH for
iodoform test.
The compound was a clear liquid. It is insoluble in water. tests
positive for DNPH test, positive for CrO3 test and negative for
iodoform. These results tell me...
