What happens when zinc carbonate is heated in the absence of air?
ZnCO3 --------> ZnO + CO2.It is an example of decomposition reaction.Colour of zinc oxide produced is yellow when hot and white when cold.
What replaces heated air at the equator?
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Is heated plutonium a chemical reaction when heated?
A reaction of oxydation with the oxygen from air.
How does zinc behave and react?
Zinc is a bluish-white metal that is relatively stable in air, forming a protective oxide layer. It reacts with acids to produce hydrogen gas and with bases to form zincates. At high temperatures, it can react with oxygen to form zinc oxide.
When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
Which volume of sulfur dioxide is formed when 9.7 g of zinc sulphide is heated in air?
The balanced chemical equation for this reaction is: ZnS + 3O2 → ZnO + 2SO2. From the equation, we can see that 1 mol of ZnS produces 2 mol of SO2. First, calculate the moles of ZnS: Molar mass of ZnS = 65.38 g/mol Moles of ZnS = 9.7 g / 65.38 g/mol Then, use the mole ratio to find the moles of SO2 produced and convert it to volume using ideal gas law if needed.
What happens when ZnCO3 is heated in the absence of air?
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.
How is zinc taken from zincblende?
1)Zinc ore is concentrated by the process named forth floation to about 55% 2 )concentrated ore is roasted in the presence of air to convert the ore into Zinc Oxide ZnS + O2 ---> ZnO + SO2 3 )Zinc Oxide is reduced to zinc in the furnace by coke ZnO + C ---> Zn + CO2
What happens when zinc carbonate is heated in the absence of air?
ZnCO3 --------> ZnO + CO2.It is an example of decomposition reaction.Colour of zinc oxide produced is yellow when hot and white when cold.
When air is heated air pressure decreases because the molecules?

does thunder causes lighting?
Yes, the energy of the lightning is converted to Heat. The heated air around the lightning expands explosively, and creates the sound waves that you hear as Thunder.
How air get heated in atmosphere?
air gets heated with carben dioxid and the rays of the sun
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
What are 4 convections?
the air being heated from a fireplace,air from a furnace,boiling water,the air being heated in a hot air balloon.
Causes atmospheric air to be rapidly heated?
There are a few causes that lead to atmospheric air to be rapidly heated. Having a fire burning will lead to rapidly heated atmospheric air.
