Question

Please help me with question #2:

How do you determine if there is a linear relationship between NaCO3 used and CO2 produced?Discuss your results in terms of moles.
Thank you!!







Question #1 :
1. Record the amount of CO2 produced versus the amount of Na2CO3 used.


Answer :

1.The amount of CO2 produced versus the amount of Na2CO3 used:

Amount of Na2CO3 used (g). vs. Amount of CO2 produced (mL)
1 g 20.28 -20.28 = 0.00mL
2 g 20.55 -20.53 = 0.02mL
4 g 20.95 -20.84 = 0.11mL
6 g 21.29 -21.14 = 0.15mL
8 g 22.16 -22.01 = 0.15mL
10 g 23.14 -22.90 = 0.24mL
12 g 23.96 -23.69 = 0.27mL



Question #2 :
Discuss your results in terms of moles. Is there a linear relationship between the amoung of Na2CO3 used and the amount of CO2 produced?

Answer 1

I don't know what all of the numbers mean since spacing is a problem here but I think what you want to do is to plot moles Na2CO3 used vs moles CO2 produced and see if you obtain a linear plot. If the mL you show is mL CO2, I would assume that also includes H2O so I would correct volume CO2 to make it dry CO2 an correct for pressure to make it moles dry CO2 at STP
