You are performing an experiment in the lab and have reactant a and reactant b. the total mass of
both reactants before the experiment is 15.0 grams. you place the reactants in an open beaker to react
without a lid. the beaker is cold to the touch afterward. you measure the product in the container and
only get a mass of 12.4 grams. what happened to the rest of the mass?
check all statements that are true.
some of the reactants were spilled.
one of the products was possibly a gas.
some of the products changed to pure energy.
ergy.
some of the products were released to the surrounding environment.
the reactants naturally produced less product because of the elements used.
