Explanation:

1. A blank in which you don't make all treatments as in the sample is called reagent blank

2. The range where a concentration can be measurable is called as dynamic range.

3. When you complete your work doing treatment of the measured values. Tht is results.

4. The blank exposed to the environment is the field blank.

5. Raw data are the primary measured values.

6. Based on Lambert-Beer law, there is an interval in which concentrations are linear regard to response of the detector, that is linear range

7. The interval that hast linearity, accuracy and precision is called range

8. When you make all treatment to the blank as in the sample is called method blank

9. When you apply an method to determine a value of your sample is called treated data

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
