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.

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.
