When potassium chromate reacts with sulfur dioxide, potassium sulfate and chromium sulfate are formed. This reaction may produce a yellow precipitate of elemental sulfur. The overall reaction is as follows: K2CrO4 + SO2 → K2SO4 + Cr2(SO4)3.
Sulphur combines with oxygen to form sulphur dioxide. S + O2 -> SO2
When sulphur is heated in the test tube in the absence of air the sulphur will break down and form a red-brown liquid. If oxygen comes into play sulphur dioxide is produced, however you should not that sulphur dioxide is a highly toxic gas and should only be produced in small amounts under a fume hood.
When carbon dioxide (CO2) is washed with potassium permanganate (KMnO4) water, the KMnO4 will be reduced by the CO2 to form a brown precipitate of manganese dioxide (MnO2). This reaction can be used to determine the presence of CO2 in a gas sample by observing the color change from purple (KMnO4) to brown (MnO2).
Sulfur is melted.
When sulfur powder is burned in air, it combines with oxygen to form sulfur dioxide gas. This reaction produces a blue flame and releases heat energy. Additionally, sulfur dioxide gas can react with water in the air to form sulfuric acid, which may create a pungent odor and cause air pollution.

2ZnS + 3O2 ---> 2ZnO + 2SO2 Zinc sulphide + Oxygen ---> Zinc oxide + Sulphur dioxide This reaction is endothermic and requires a heat change (H) in order to happen. As the Zinc sulphide reacts with the oxygen the zinc becomes oxidised (oxidation, zinc atoms bond to oxygen atoms), and during this reaction sulphur dioxide is given off.

The result would lead to the second coming of Jesus.

Lead dioxide decomposes upon getting heated.
Nothing
When you smoke, ride a vehicle, or use electricity, you let out carbon dioxide.
nothing will happen at all
