If the mass of a chemical reaction's product is 15 grams, what would the mass of the reactants be?
20 g
15 g
10 g
3 g
Which section represents the reactants?
A
B
C
Why does this picture demonstrate the Law of Conservation of Mass?
the number of atoms of each element are the same on both sides
they start out separate and end up combined
the same elements are used
it doesn't demonstrate the Law of Conservation of Mass
If a chemical reaction occurs in a closed system (no way for any part of the reaction to escape), how does the product mass compare to the reactant mass?
the mass would decrease
the mass would increase
the mass would stay the same
it depends on the type of reaction
Which picture below would correctly demonstrate the Law of Conservation of Matter if this picture is the reactants?
