What happens when ZnCO3 is heated in the absence of air?
When ZnCO3 is heated in the absence of air, it undergoes thermal decomposition. This results in the formation of zinc oxide (ZnO) and the release of carbon dioxide gas (CO2).
Which substance gives sulphur dioxide when heated in air?
Burning sulfur-containing materials, such as coal, oil, or natural gas, releases sulfur dioxide when heated in air.
When coal is heated in the absence of air what is the gas called?
The gas produced when coal is heated in the absence of air is called coal gas. It is a mixture of various gases such as methane, hydrogen, carbon monoxide, and carbon dioxide.
What happen ton sulphar when slightly heated in test tube by a Bunsen burner?
When sulfur is slightly heated in a test tube by a Bunsen burner, it will melt to form a pale yellow liquid. Once the temperature is raised further, the liquid sulfur will start to vaporize and emit a characteristic odor. If the heating is continued, the sulfur may eventually catch fire and burn with a blue flame, forming sulfur dioxide gas.
What happens when S is heated in the absence of air?
When S (sulfur) is heated in the absence of air, it undergoes sublimation, meaning it changes directly from a solid to a gas without passing through a liquid state. This process results in the formation of a colorless gas with a characteristic odor of sulfur dioxide.
What happens when sulphur is heated in absence of air?
Sulfur is melted.

What will happen when coal is burned in the absence of air?
It will not burn.
What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
What happens when S is heated in the absence of air?
When S (sulfur) is heated in the absence of air, it undergoes sublimation, meaning it changes directly from a solid to a gas without passing through a liquid state. This process results in the formation of a colorless gas with a characteristic odor of sulfur dioxide.
What will happen to the air in the air tight container when you heated it in the microwave oven?
the air in the container expands
What will happen to air if it is heated along a slope element?
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.
What happens if you add a carbonate to acid or when you heat a carbonate?
when the carbonate is heated in absence of air then the CO2 is produced as the byproduct .
Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
