But the x-axis was discrete data. How could that be a line graph?
But a line graph is most suitable as it lets us see the overall trend, yes? It's easier to interpret that way, especially because in the next question, we were asked to give an estimate for some C3H7OH, I think. How could you have gotten an estimate using a bar graph?
Test for OH is universal indicator turning purple/blue Ugh forgot about K2CO3, wrote K2O instead Messed up on conversion from G to F Incomplete combustion is invalid as mass of alcohol burnt is lower so no. of moles of alcohol is lower. Delta H= energy divided by moles so if moles is smaller, Delta H would be higher thus its invalid. The only valid point was heat loss. Hoping for 45 :/
And do you remember was this question before or after the haloalkane ( E F G) one ?
It was part of the same question. Like the first part, we had to name E I think. The next had to do with the test for the -OH group, if my memory serves me right The haloalkane one came after this part. Towards the end.

OH observation is universal indicator turning purple. Dammit forgot about K2CO3, wrote K2O instead Incomplete combustion is invalid since this would mean mass of alcohol burnt would be lower thus no. of moles of alcohol would be low. Delta H = Energy divided by moles so lower moles means higher Delta H thus its invalid Messed up on conversion from G to F Hoping for around 45 :/
Unit 6 is on Friday. I'm more nervous about that :/ I mean, writing that 10 mark answer needs a lot of thinking and stuff And I do hope for the second question, they don't introduce some new mathematical concept.
