When zinc is heated, it may react with oxygen in the air to form zinc oxide, which can appear white or yellowish initially. However, if the zinc is heated further, it can produce zinc oxide in a different crystalline form, which may appear greenish due to the presence of impurities or variations in the material. Additionally, if the zinc is exposed to moisture or other contaminants, it can develop a greenish patina similar to what occurs with copper oxidation.
What else can I help you with?
What is the name of the substance created when zinc is heated with sulphur?
The substance created when zinc is heated with sulphur is zinc sulfide.
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.
How do you get zinc from zinc blende?
Zinc can be obtained from zinc blende (also known as sphalerite) through a process called roasting. First, the zinc blende is heated in the presence of oxygen to convert it into zinc oxide. Then, the zinc oxide is further heated with coke (a form of carbon) to reduce it to metallic zinc, which can be collected for further use.

When zinc solution is burned what flame color is observed?
When a zinc solution is burned, a blue-green flame color is typically observed. This flame color is due to the presence of zinc in the solution, which emits specific wavelengths of light when heated.
What is observed when zinc nitrate is heated?
it should be heated at 500°c
What is the chemical name for white powder when zinc in heated?
zinc(II) oxide
What compound decomposes when it is heated to zinc oxide?
Zinc carbonate decomposes when heated to form zinc oxide and carbon dioxide. This reaction occurs due to the thermal decomposition of zinc carbonate at high temperatures.
