Reactants Initial mass (g) Final mass (g) Change in mass (g) Copper chloride + aluminum 18.2 0.1 Copper chloride + sodium hydrogen phosphate 0.0 Was mass conserved in the first reaction between copper chloride and aluminum? Explain the evidence in the chart and what you know about the law of conservation of mass.
