Question

Ca → Ca(OH)2 → CaCO3 → CaO → CaSO4 → CaCl2

Answer 1

Ответ:

1. Ca + 2OH = Ca(OH)2
2. Ca(OH)2 + H2CO3 = CaCO3 + 2H2O
3. Zn + CaCO3 = CO + CaO + ZnO
4. CaO + H2SO4 = CaSO4 + H2O
5. CaSO4 + 2NaCl = Na2SO4 + CaCl

Объяснение:

Answer 2

→ Ca(NO3)2

This is a possible sequence of reactions involving calcium (Ca) that can result in the formation of calcium nitrate (Ca(NO3)2). However, it is important to note that the conditions and specific reactants involved can affect the outcome of each step. Furthermore, there may be alternative paths to produce calcium nitrate.
