Why is sulfur-dioxide reducing while tellurium-dioxide is oxidising agent?
S+O2->SO2 Oxidation no. of sulphur changes from 0 to +4. Due to presence of d-orbitals(vacant) sulphur can extend its covalency & show oxidation states till +6, which is stable in sulphur (eg: SF6). Hence it acts as a reducing agent. Te+O2->TeO2 Oxidation no. of Te changes from 0 to +4. Unlike sulphur Te cannot show +6 oxidation state as it is highly unstable due to inert pair effect. Therefore there can only be a decrease in it oxidation state (it can decrease to -2, +2). Hence it acts as an oxidising agent.

How does water act as an agent of soilerosion?
When it rains heavily and there is flooding, water acts as an agent of soil erosion by carrying away the top layer of soil.
Why is sulphur harmful to the atmosphere?
Sulphur bind with oxygen and helium to make SO2 and H2S which are foul-smelling, toxic compunds. It burns to create sulphur dioxide which is an irritating gas that causes breathing problems. Sulphur also makes acid rain whicch corrodes buildings.
Is propane an oxidizing agent?
No it is not. Propane can be used as fuel during oxidation reaction however it is not an oxidizing agent. In a redox reaction such as combustion, propane acts as a reducing agent. Common agents are O2 and O3.
What is role of sulphuric acid in dehydration of ethanol?
Acts as the dehydrating agent (catalyst).
Why is sulfuric acid a dehydrating agent?
I think, it acts as a dehydrating agent because it has a great affinity for water...and in my opinion the reason behind it's great affinity is that water decomposes the acid...
What is the Dual role of sulfuric acid in the copper cycle?
It speeds up the reaction, and acts as a dehydrating agent

Why does silicon dioxide use as an ingredient in coffee?
Silicon Dioxide acts as an anticaking agent in powdered foods
Is molasses vegetarian?
Yes. It is made from young sugar cane. Sulphur dioxide, which acts as a preservative, is added during the sugar extraction process.
What effect does vcarbon dioxide have on the ozone layer?
Carbon dioxide acts as a greenhouse agent. It causes greenhouse affect which then causes ozone depletion.
Which planet has an atmosphere of carbon dioxide gases that acts as a blanket not allowing heat to escape?
Venus has an atmosphere of 96% carbon dioxide. It is also completely covered with clouds consisting of droplets of concentrated sulphuric acid. These cloud tops also show traces of sulphur dioxide, solid sulphur and chlorine. The surface temperature is 460oC (860oF).
Where is the ozone bad?
Bad ozone is the ozone present at the surface of the earth. It is because the ozone at the surface of earth acts as a air pollutant resembling like carbon dioxide, carbon monoxide, sulphur dioxide etc.
What is the function of sulfuric acid in the esterification reaction?
Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
What is the chemical equation to show that sulfur dioxide gas acts as a reducing agent?
2H2S(g) + SO2(g) --> 2H2O + 3S Fe2O3 catalyst and temperature 673K
