The complete combustion reaction for C16H34 would be as follows:
C16H34 + 17/2O2 ------> 16CO2 + 17H2O
We are given the amount of oxygen to be used for the reaction. This value would be the stating point for the calculations.
0.50 mol O2 ( 1 mol C16H34 / 17/2 mol O2 ) ( 22.4 L / 1 mol ) = 1.317 L = 1317 mL C16H34
I'd guess A or D, but my gut says A
Answer:
Accuracy of values
Explanation:
They're correct due to margin error of ±0.5 during an experiment.
1 min 15 seconds is equivalent to 75 seconds.
However the other one was 75.5 seconds.
Using the margin error of ±0.5 during recording, they're both correct.
Note : Accuracy is the closeness of agreement between a measured value and a true or accepted value. Measurement error is the amount of inaccuracy.
Precision is a measure of how well a result can be determined (without reference to a theoretical or true value). It is the degree of consistency and agreement among independent measurements of the same quantity; also the reliability or reproducibility of the result.
The uncertainty estimate associated with a measurement should account for both the accuracy and precision of the measurement.
In this case, this is an argument of who was more accurate and judging by this standard, they're both accurate but not necessarily precise since their values are not exact with each other.
In science, we have a name for this, called Avogadro's number, and it describes the number of representative particles in one mole of a substance. The inverse mole unit tells us there are 6.022×1023 particles of something *per mole* so there are 1,023 particles
