ZnCO3 --------> ZnO + CO2.
It is an example of decomposition reaction.
Colour of zinc oxide produced is yellow when hot and white when cold.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
when zinc carbonate is heated it' white colour changes to yellow . And when it is cooled it again changes to it original colour
The chemical formula of zinc carbonate is ZnCO3.
what happens to calcium oxide and zinc oxide when heated?
When zinc reacts with calcium carbonate, it typically involves a displacement reaction where zinc displaces calcium, forming zinc carbonate and calcium metal, although this reaction is not common under standard conditions. In the presence of heat, the calcium carbonate can decompose, releasing carbon dioxide and forming calcium oxide, while zinc may form zinc oxide if it oxidizes. Overall, the direct reaction is complex and may not occur significantly in normal conditions without additional factors like heat or specific environments.
Zinc carbonate decomposes when heated to give zinc oxide.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
carbon dioxide, when carbonates are heated carbon dioxide is is given off.
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.
when zinc carbonate is heated it' white colour changes to yellow . And when it is cooled it again changes to it original colour
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.
it explodes

The carbonates that can be thermally decomposed . They form metal oxides and carbon dioxide. When white zinc carbonate powder when heated forms yellow/white zinc oxide and carbon dioxide gas: the balanced equation for zinc carbonate--------carbon dioxide zinc oxide is :ZnCO3 → ZnO + CO2
Zinc carbonate is a scientific name.
One way to make zinc carbonate is by reacting a soluble zinc salt (such as zinc sulfate or zinc chloride) with a carbonate salt (such as sodium carbonate or sodium bicarbonate) in a solution. The zinc carbonate will precipitate out of the solution as a solid, which can then be filtered and dried.
The chemical formula of zinc carbonate is ZnCO3.
