Compare the mass ratios of N2O3 and N2O5 and prove the law of multiple proportions holds true.
I'm having trouble understanding what the question is asking for. So far, I've done this:
N2O3:
N: 14g * 2 = 28g
O: 16g * 3 = 48g
N2O5:
N: 14g * 2 = 28g
O: 16g * 5 = 80g...
I did attempt it on my own. I was hoping someone would explain it to me though.
I used Q(rxn) = Q(water) + Q(calorimeter)
Also expanded: Q (rxn) = -[(m*s*change in temp.) + (C*change in temp.)]
= -[(1200*4.184*3.06) + (10400*3.06)] <---- I changed things...
Calorimetery Problem. :( It's not a homework but I can't get the answer.
0.510 g of ethanol is burned in a flame calorimeter (constant pressure) containing 1200 g of water. The water is initially 22.46 C and is warmed up to 25.52 C as a result of the reaction. The heat capacity of the...
Thanks for answering my questions. :)
So would this mean that if you were to attempt exciting a specific atom (that emits a specific colored light at high temperatures) at low temperatures, the photons (if any were emitted) would produce a different color light?
What I meant was an...
I've never really taken any chemistry before so I'm currently taking a class and the more I learn about it, the more interesting it becomes. :smile: However, I do have a few questions (you might find simple) that are kind of bugging me as we begin to progress through the chapters...
1. When...
