Write the chemical equations of the following reactions. (1) The poem in Yu Qian's Poem of Lime: "Burning with fire is idle" represents the chemical reaction of _ _ _ _ _.

(1) "If a fire burns carelessly" reflects the chemical reaction that calcium carbonate, the main component of limestone, decomposes at high temperature to produce calcium oxide and carbon dioxide. The chemical equation of this reaction is: CaCO3? High temperature? . ? CaO+CO2↑。

(2) slaked lime reacts with copper sulfate solution to generate copper hydroxide precipitate and calcium sulfate. The chemical equation of the reaction is: Ca (OH) 2+CuSO4 ═ Cu (OH) 2 ↓+CaSO4.

So the answer is: (1)CaCO3? High temperature? . ? CaO+CO2↑； (2)Ca(OH)2+CuSO4═Cu(OH)2↓+CaSO4.
