In an attempt to study the variation of the boiling point of mixture (B + C), the teacher immerses a thermometer probe into the mixture inside the test tube. Then, she connects the probe to the computer interface and starts collecting temperature data during the boiling phase. After 10 minutes, a graph is obtained. To which physical state will the above mixture change after boiling? Which of the above graphs do you expect to obtain? why?

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
