Question

1. The crucible is not fired, as the procedure suggests. The mass of the dirty crucible is recorded. However, the impurities are burned off in the experiment. Will the reported mass of the final product be too high, too low, or unchanged as a result of this technique error?

Answer 1

Answer:

The mass of the final product will be too high

Explanation: do to not firing off the impurities before weighing.

If there is dirt left over on the crucible from the last experiment, it has retained some impurities from this previous use. The “dirty” pass is recorded, and the impurities are burned off.
