- 11. The table below shows the properties of calcium metal. Appearance & Silvery white Melting Point & 842^circ mathrm(C) Reactivity & Reacts moderately with cold water and vigorously with acids Density & 1.55 mathrm(~g) / mathrm(cm)^3 Which statement characterizes the properties of calcium based on the table? A The appearance of calcium is a physical property because its color depends on chemical changes. B. The melting point of calcium is a physical property because measuring it produces a chemica reaction. C. The reactivity of calcium is a chemical property because it involves a change in the chemical composition. D. The density of calcium is a chemical property because changing the density involves making calcium into another element.
