What else can I help you with?
What will happen if hydrogen gas is heated over copper oxide?
the copper oxide will turn red
Will a reaction occur when copper is heated with iron oxide?
Yes, a reaction will occur when copper is heated with iron oxide. The iron in iron oxide will react with the copper to form copper oxide and iron.
What solid residue will turn from green to black if heated?
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.
When copper is heated in air?
When copper is heated in air, it undergoes oxidation and forms copper oxide. Initially, a layer of black copper oxide (CuO) forms on the surface, and upon further heating, it turns into red copper oxide (Cu2O).
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
When copper is heated in oxygen the compound formed is?
When copper is heated in oxygen, the compound formed is copper oxide.
When copper carbonate is heated what ionic compound remains?
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
When copper is heated what products are formed?
When copper is heated, it undergoes oxidation and forms copper oxide as the main product. If the heating is carried out in the presence of oxygen, copper oxide (CuO) is formed. If the oxygen is limited, copper(I) oxide (Cu2O) can also be formed.
What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
Why did the penny turn gold when heated in the burner in the burner flame?
When a penny is heated in a flame, the copper metal reacts with oxygen in the air to form copper oxide. Copper oxide has a black color, but when it is heated at high temperatures, it can react with carbon in the flame to form a thin layer of elemental gold on the penny's surface, giving it a gold color.
Does copper oxide decompose when heated?
Yes, copper oxide decomposes when heated to high temperatures, typically above 800°C, into copper and oxygen. This process is a thermal decomposition reaction.
What gas is formed when copper sulfate is heated?
When copper sulfate is heated, it decomposes to form copper oxide and sulfur dioxide gas.
