What does copper react with when heated and what is formed as a result?
(When you put copper underneath a fire, would the copper be reacting with oxygen or carbon dioxide?)
i think it's oxygen because carbon-dioxide rises since it's hotter than the surrounding air coming from the bottom.
When copper is heated, it reacts with oxygen in the air to form copper(II) oxide. The reaction is as follows:
2 Cu (s) + O2 (g) → 2 CuO (s)
This means that copper reacts directly with oxygen, not carbon dioxide, when it is heated. To determine this, we need to understand the reaction between copper and oxygen and how to balance the equation.
You can find this information by consulting a reliable source such as a chemistry textbook, online databases, or educational websites. These resources will provide you with the necessary equations and explanations of chemical reactions involving copper and oxygen.
