Answer to: brass, an alloy (mixture) of Zn and Cu, reacts with HCl to form zinc(II) chloride and H2 gas. Relevance. Answer Save. Cu does not react. all ions are released from all compounds, all ions are spectators. It requires 5 liters of 0.4 M HCl to react completely with 40 g of calcium. Copper sulfate is quite soluble in water, so it is dissociated into copper (II) ions and sulfate ions, as is hydrochloric acid, and copper (II) chloride. Na2CO3 reacts with HCl in the chemical equation: Na2CO3(s) + 2 HCl(aq) = CO2(g) + H2O(l) + 2 NaCl(aq). copper metal is a spectator solid. Hiện tượng quan sát được là A.
