A student performed the experiment in this module but failed to follow the procedure exactly, keeping the crucible completely covered during the entire heating and cooling processes. Be specific. 1. Explain the probable effect of this procedural change on the experimental results.
2. Would the student's calculated percent water in the hydrate be high, low, or unaffected? Briefly explain

This question is incomplete

Explanation:

This question is incomplete but the answer to the question can be correctly predicted from the available information from the question.

1. If a "container" (in this case a crucible) is closed throughout a heating experiment. Then it must be noted that water vapor will not be able to escape during the course of the experiment. The water vapor will form a "cloud" of water droplets under the cover of the crucible. And when this crucible is cooled, this water droplets return back to the content/substance inside the crucible.

2. When compared with the initial amount of water present in the substance in the crucible, the percentage of water "left" in the hydrate or substance in the crucible would be high. This is because the water vapor that was suppose to leave the crucible did not leave because the crucible was closed (thus causing very low amount of water vapour to leave).

let that person have a turn to speak : )
