Question

C-CO2-CaCO3-CuO-Ca(OH)2-Ca(PO)4

Answer 1

C + O2 -> CO2 (t)
CO2 + Ca(OH)2-> CaCO3 + H2O
CaCO3 -> CaO + CO2↑ (t)
CaO+ H2O -> Ca(OH)2↓
3Ca(OH)2 + 2H3PO4 -> Ca3(PO4)2 + 6H2O

Answer 2

The chemical sequence you provided appears to represent a series of reactions or transformations involving different compounds. Here's a breakdown of the sequence:

1. C: Carbon
2. CO2: Carbon dioxide
3. CaCO3: Calcium carbonate (also known as limestone or chalk)
4. CuO: Copper(II) oxide
5. Ca(OH)2: Calcium hydroxide (also known as slaked lime or hydrated lime)
6. Ca(PO)4: The notation seems incomplete or incorrect. Typically, calcium phosphate is represented as Ca3(PO4)2 or Ca3(PO4)2·xH2O.

It's important to note that chemical reactions often involve more than one step and may require specific conditions such as temperature, pressure, or catalysts. Without further context or information, it's difficult to determine the specific reactions or processes that could occur between these compounds. If you provide more details about the intended context or purpose, I'll be happy to assist you further.
