A- law of conservation of energy
Answer: C) middle 50 percent of the data
The interquartile range (IQR) spans from the first quartile Q1 to the third quartile Q3.
25% of the data is below Q1 and 75% of the data is below Q3. The gap between the two endpoints consists of 75-25 = 50 percent of the data, or half of the data.
3NO₂ + H₂O→2HNO₃ + NO
n(NO)=n(NO₂)/3
n(NO)=0.83/3=0.277 mol
