In an experiment, a scientist placed two chemicals in a sealed container as seen in the picture below. Before mixing the two reactants, she determine
the total mass of the flask and its contents. After determining the total
mass, she mixed the two chemicals to allow the chemical reaction to
occur. She then placed the flask and its contents back on the balance as
seen below. Which represents the BEST prediction to the second scale
reading after the reaction?
