Question

Cu (NO3)2=NO2=KNO3=O2=CO2=

Answer 1

2Cu(NO3)2 = 2CuO + O2 + 4NO2
2KOH + 2NO2 = KNO2 + KNO3 + H2O
2KNO3 = 2KNO2 + O2
C + O2 = CO2

Answer 2

It seems like there is a mix-up of chemical formulas and symbols in your input. Let me try to clarify and provide the correct chemical formulas and reactions:

1. Cu(NO3)2: This is the chemical formula for copper(II) nitrate, which is a blue crystalline solid.

2. NO2: This is the chemical formula for nitrogen dioxide, a reddish-brown gas with a pungent odor.

3. KNO3: This is the chemical formula for potassium nitrate, a white crystalline solid commonly known as saltpeter.

4. O2: This is the chemical formula for molecular oxygen, a colorless gas that is essential for life.

5. CO2: This is the chemical formula for carbon dioxide, a colorless and odorless gas produced during respiration and combustion processes.

Now, it seems like you are trying to connect these chemical formulas with the '=' symbol, which usually represents a chemical reaction. However, the provided formulas don't form a balanced chemical equation. If you have a specific chemical reaction in mind or need further clarification, please provide more context or details.
