Question

At reaction's completion, equalize liquid heights. Zoom in on eudiometer and use up/down arrow to raise or lower eudiometer Measure volume of hydrogen gas.

Answer 1

To measure the volume of hydrogen gas in the eudiometer, you need to equalize the liquid heights at the completion of the reaction. Then, measure the volume using the graduations on the eudiometer.

Step-by-step explanation:

To measure the volume of hydrogen gas in the eudiometer, you need to equalize the liquid heights at the completion of the reaction. This ensures that the gas occupies the same volume as the displaced liquid. To do this, zoom in on the eudiometer and use the up/down arrow to raise or lower it until the liquid heights are equal. Then, measure the volume of the hydrogen gas using the graduations on the eudiometer.
