Consider the reaction
C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l) , ΔH = -1.37 × 103 kJ
When a 15.7-g sample of ethyl alcohol (molar mass = 46.1 g/mol) is burned, how much energy is released as heat?
Regression Line

Residuals
The differences between observed values and the values predicted by a model.
Confidence Interval
An aggregate of values, concluded from statistical review of samples, assumed to likely house the unknowable value of a population parameter.
Prediction Interval
A range of values that is likely to include the value of an unknown parameter for a future observation with a specified probability.
