A student performs an experiment to determine the melting point of ice in order to investigate the strength of electrostatic forces between its molecules. Once the student completes the experiment, which additional action should the student take?(1 point)
The student should perform multiple trials of the same experiment, then take the average of all of the results.
The student should perform experiments using different amounts of ice, then use the result closest to 0ºC.

Thumbs up if u hate school👍
Never mind, just took test it is A.
Pls help with this question. I think its A but please correct me if im wrong.
Use the chemical equation to answer the question.
WO3(s) + 3H2(g) → W(s) + 3H2O(g)
Which statement correctly describes the reaction?
Ans: Tungsten (W) changes oxidation numbers from +6 to zero, so it undergoes reduction.

The correct answer is: The student should perform multiple trials of the same experiment, then take the average of all of the results.
Explanation:
Performing multiple trials of the same experiment helps to minimize the impact of potential errors or inconsistencies in the measurements. By repeating the experiment several times, the student can obtain a range of results and calculate an average. This average will provide a more accurate representation of the melting point of ice and also reduce the influence of any outliers or random errors.
