Synthesis
CuSO4 is light blue and liquid Sulfur is yellow and powdery Copper is hard
Decomposition MnO2 is black and powdery H2O2 is clear, no bubbles Single Fe is black Displacement and its on the bottom CuSO4 was light blue liquid Double Na2CO3 is Displacement clear and liquid CuCl2 is light blue and liquid Combustion Thick gluey Substance smells
Factors Reaction Rate Color Catalystchange CuSO4 Odor change Temperature
Cu turns black CuSO4 bubbles up and still light blue and liquid Sulfur stays the same It bubbles, Gas release looks brownish black
Catalyst H2O2
Fe turned red Color FeSO4 change turned clear liquid
