Is sulfur in this chemical reaction a oxidation agent or reduction agent in S plus H2 plus 2O2 --- H2SO4?

It is safer to claim it as neither - not least because the reaction would/does not work. Far safer to say that the sulphur is oxidised (which, you could argue, makes it a reducing agent).

Which element undergoes Oxidation in k2cro4 na2so3 hcl-kcl na2so4 crcl3 h2o?
Chromium undergoes oxidation in the given chemical equation. In this reaction, chromium changes from a +6 oxidation state to a +3 oxidation state, indicating that it has lost electrons and undergone oxidation.
Is formation of silver sulfide when silver reacts with sulfur in the air a physical change?
No, the formation of silver sulfide when silver reacts with sulfur in the air is a chemical change. This is because new substances with different properties are formed during the reaction.
When sulfur burns what indicates a chemical chang has occurred?
The production of sulfur dioxide gas and the release of heat and light indicate that a chemical change has occurred when sulfur burns. These changes are evidence of the chemical bonds in sulfur molecules breaking and forming new substances during combustion.
When something combines with oxygen is it a physical or chemical property of sulfur?
When sulfur combines with oxygen, it undergoes a chemical reaction to form sulfur dioxide. This is a chemical property of sulfur because it involves a change in the chemical composition of the substance.
How many sulfur atoms are in the chemical reaction H2S plus SO2 plus H2?
In the chemical reaction H2S + SO2 + H2, there are a total of 3 sulfur atoms present. One sulfur atom comes from the H2S molecule, one from the SO2 molecule, and none from the H2 molecule.
Is burning sulfur a physical or chemical change?
It is a chemical change, an oxidation reaction.
Hydrochloric acid reacts with sulfuric acid?
Hydrochloric acid and sulfuric acid will react to form hydrogen chloride gas and sulfuric acid. This reaction typically takes place in a two-step process where the initial reaction forms hydrochloric acid and sulfuric acid, which then reacts further to produce hydrogen chloride gas and sulfuric acid.

What is the sulfur cycle?
Sulfur is one of the constituents of many proteins, vitamins and hormones. It recycles as in other biogeochemical cycles.The essential steps of the sulfur cycle are:Mineralization of organic sulfur to the inorganic form, hydrogen sulfide: (H2S).Oxidation of sulfide and elemental sulfur (S) and related compounds to sulfate (SO42-).Reduction of sulfate to sulfide.Microbial immobilization of the sulfur compounds and subsequent incorporation into the organic form of sulfur.These are often termed as follows: Assimilative sulfate reduction (see also sulfur assimilation) in which sulfate (SO42-) is reduced to organic sulfhydryl (otherwise known as thiol) groups (R-SH) by plants, fungi and various prokaryotes. The oxidation states of sulfur are +6 in sulfate and -2 in R-SH. Desulfuration in which organic molecules containing sulfur can be desulfurated, producing hydrogen sulfide gas (H2S), oxidation state = -2. Note the similarity to deamination. Oxidation of hydrogen sulfide produces elemental sulfur (So), oxidation state = 0. This reaction is done by the photosynthetic green and purple sulfur bacteria and some chemolithotrophs. Further oxidation of elemental sulfur by sulfur oxidizers produces sulfate. Dissimilative sulfur reduction in which elemental sulfur can be reduced to hydrogen sulfide. Dissimilative sulfate reduction in which sulfate reducers generate hydrogen sulfide from sulfate.Human impact on the sulfur cycle is primarily in the production of sulfur dioxide (SO2) from industry (e.g. burning coal) and the internal combustion engine. Sulfur dioxide can precipitate onto surfaces where it can be oxidized to sulfate in the soil (it is also toxic to some plants), reduced to sulfide in the atmosphere, or oxidized to sulfate in the atmosphere as sulfuric acid, a principal component of acid rain
Give you five substances that undergoes oxidation reaction?
Iron: Iron can oxidize in the presence of oxygen to form iron oxide (rust). Hydrogen: Hydrogen gas can undergo oxidation reactions to form water when combined with oxygen. Copper: Copper can undergo oxidation reactions to form copper oxide. Ethanol: Ethanol can undergo oxidation reactions to produce acetic acid. Sulfur: Sulfur can undergo oxidation reactions to form sulfur dioxide or sulfur trioxide.
How many sulfur atoms are in the chemical reaction H2S plus SO2 plus H2?
In the chemical reaction H2S + SO2 + H2, there are a total of 3 sulfur atoms present. One sulfur atom comes from the H2S molecule, one from the SO2 molecule, and none from the H2 molecule.
What is the chemical equation for reduction of sulfur dioxide using lime?
You put the lime in the coconut.
What is Manganese2 and Sulfur3?
Manganese(II) is a chemical compound where manganese has a +2 oxidation state. It is an important nutrient for various biological processes and is commonly found in foods and supplements. Sulfur(III) is not a commonly encountered oxidation state of sulfur in chemical compounds. The most common oxidation states of sulfur are -2, +4, and +6. It is important in many biological processes and is present in various compounds, such as sulfur dioxide (SO2) and sulfur trioxide (SO3).
Sulfur has a bright yellow color is this physical or cheimical property?
Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.
Where was sulfur made?
You can't make sulfur - it is an element, you can only mine, refine or produce it by chemical reaction. The majority of elemental sulfur in trade today is a byproduct of the petro-chemical/refining industry.
Why is the oxidation number of Sulfur never higher than 6?
In chemical bonding, only the valence shell electrons participate in reactions in general conditions. Sulfur has 6 electrons in its third energy level, outermost shell. Therefore the highest oxidation number for sulfur is +6.
