Question

Допишите уравнения и их названия.CuSO4+Pb,Ca+O2,Mg+H2,K+H2O,Zn+H2​

Answer 1

Pb + 2CuSo4 → Pb(So4)2 + 2Cu (сульфат свинца)

2Ca + O2 → 2CaO (оксид кальция)

Mg + H2 → MgH2 (гидрид магния)

2K + 2H2O → 2KOH + H2 (гидроксид калия)

Zn + H2 → ZnH2 (гидрид цинка)

Answer 2

Chemical Equations and Their Names

1. CuSO4 + Pb - The chemical equation is: CuSO4 + Pb → Cu + PbSO4 - This is a single displacement reaction where copper displaces lead in the compound to form copper and lead(II) sulfate.

2. Ca + O2 - The chemical equation is: 2Ca + O2 → 2CaO - This is a synthesis reaction where calcium reacts with oxygen to form calcium oxide.

3. Mg + H2 - The chemical equation is: Mg + H2 → MgH2 - This is a synthesis reaction where magnesium reacts with hydrogen to form magnesium hydride.

4. K + H2O - The chemical equation is: 2K + 2H2O → 2KOH + H2 - This is a single displacement reaction where potassium displaces hydrogen in water to form potassium hydroxide and hydrogen gas.

5. Zn + H2 - The chemical equation is: Zn + H2 → ZnH2 - This is a synthesis reaction where zinc reacts with hydrogen to form zinc hydride.
