In which case would recalibrating a thermometer be an important next step in an experiment dealing with boiling points?(1 point)
The results of several trials vary by a large amount, but the average is close to the accepted value for the boiling point.
The results of several trials are all very close to each other, but they are noticeably different from the accepted value for the boiling point.
A small number of trials are conducted, with results quite different from each other, and with an average that is noticeably different from the accepted value.
A single trial is conducted, and the result is very close to the accepted value of the boiling point.

i honestly think its c
Agree
it’s B : the results of several trials are all very close to each other, but they are noticeably different from the accepted value for the boiling point. i just took the test
Just took the exam, here are the answers, since Quizlet won't show you all the answers right away. I'll also post the ones for the math exam after I take it!
1: Yes, it is possible because they have similar intensive properties
2: Homogeneous mixture
3: Due to repulsion between electrons, valence electrons will be arranged as FAR APART from each other as possible
4: Neutral atoms of lead must have 82 protons. Ions must have 82 PROTONS as well
5: Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.
6: A covalent bond would form because the electron would be shared so both hydrogens have a full, stable shell.
7: K and CI
8: Polar sugar molecules dissolve in WATER, which is polar.
9: High temperatures mean more kinetic energy, which keeps sodium and chlorine ions from combining, which increases solubility.
10: It accepts protons and only PARTIALLY dissociates in water.
11: PH3 is a stronger acid than NH3.
12: The scientist is investigating Charles’s law, which shows that TEMPERATURE and VOLUME are DIRECTLY proportional.
13: It will likely be unreactive.
14: Student B, because of the law of conservation of matter
15: The atoms have the same electronegativity.
16: Bromine
17: No, it will not because iodine is less reactive than chlorine.
18: 6H2O + 6CO2 → C6H12O6 + 6O2
19: +2
20: 0.24 M
21: Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes REDUCTION.
22: It has a HIGHER boiling point than water, and it likely has STRONGER electrostatic forces between its molecules than water.
23: Castor oil
24: Substance B has stronger bonds, and it takes MORE energy to undergo a phase change.
25: The student should perform multiple trials of the same experiment, then take the AVERAGE of all of the results.
26: The results of several trials are all VERY CLOSE to each other, but they are noticeably different from the accepted value for the boiling point.
