Cu+HNo->Cu(No3)2 -> No2

It looks like you're attempting to describe a chemical reaction involving copper (Cu) and nitric acid (HNO₃), along with the products that are formed, specifically copper(II) nitrate (Cu(NO₃)₂) and nitrogen dioxide (NO₂).

The balanced chemical equation for the reaction of copper with concentrated nitric acid can be represented as follows:

\[ \text{Cu} + 4 \text{HNO}_3 \rightarrow \text{Cu(NO}_3\text{)}_2 + 2 \text{NO}_2 + 2 \text{H}_2\text{O} \]

Key points about this reaction:

• Copper (Cu) is oxidized to copper(II) ions (Cu²⁺) in Cu(NO₃)₂.
• Nitric acid (HNO₃) acts as an oxidizing agent, producing nitrogen dioxide (NO₂) as one of its products.
• The reaction also produces water (H₂O) as a byproduct.

If you have any specific questions about the reaction, such as stoichiometry, types of reactions, or other related topics, feel free to ask!
