Question

Ca - CuO - CuCe2 - Cu(OH)2 - Cuo​

Answer 1

Ответ:

2Cu+O2=2CuO

CuO+2HCl=CuCl2+H2O

CuCl2+2NaOh=Cu(OH)2+2NaCl

Cu(OH)=CuO+H2O

CuO+H2=Cu+H2O

Answer 2

It looks like you've provided a sequence of chemical compounds involving different elements. Let me break down each compound for you:

1. Ca: This represents the chemical symbol for calcium, which is an alkaline earth metal.

2. CuO: This represents copper oxide, which is a compound made up of copper (Cu) and oxygen (O) atoms. It can exist in different oxidation states, such as cupric oxide (CuO) or cuprous oxide (Cu2O), depending on the ratio of copper and oxygen atoms.

3. CuCe2: This doesn't correspond to a known chemical compound. It seems like a combination of copper (Cu) and cerium (Ce) elements, but the stoichiometry and oxidation states are not clear.

4. Cu(OH)2: This represents copper(II) hydroxide, a compound composed of copper (Cu) ions and hydroxide (OH^-) ions.

5. Cuo: This seems to be a typo, likely meant to be CuO, which was mentioned earlier as copper oxide.

It's important to note that some of the combinations you've mentioned are not typical or well-defined chemical compounds. The notation CuCe2, for instance, doesn't correspond to any known chemical formula. If you have specific questions about these compounds or their properties, please provide more details or context so that I can assist you more accurately.
