Question

a student claims, the products weighed the same as the reactants because the scale was not sensitive enough to measure small losses of gas.
part a
based on the data in the table, how accurate is this claim?
the claim is accurate, because the scale cannot detect small changes in mass.
the claim is not supported, because the scale showed equal mass in every trial, even when gas was produced.
the claim is accurate, because solids weigh more than liquids, which kept the mass balanced.

Explanation:

If the scale showed equal mass in every trial even when gas was produced, it means there's no indication that the scale couldn't measure small losses of gas. The claim that the scale was not sensitive enough is not supported by the data showing equal masses in all trials.

Answer:

The claim is not supported, because the scale showed equal mass in every trial, even when gas was produced.
