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.

If you combine lead oxide and carbon together what do you get?
You get Lead and Carbon dioxide. Of course, you have to heat them. no idk help me :0
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).

How does sulfur dioxide preserve food?
Sulfur dioxide preserves food by inhibiting microbial growth and slowing down the oxidation of fats and pigments in the food. It acts as an antioxidant and antimicrobial agent, helping to extend the shelf-life of various food products.
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.
Why is sulfuric acid a dehydrating agent?
Sulfuric acid is a dehydrating agent because it has a strong affinity for water molecules. When sulfuric acid comes into contact with a substance containing water, it can react with the water molecules, pulling them away from the substance and leading to dehydration. This property makes sulfuric acid useful in many industrial processes where removing water is necessary.
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.
Why H2SO4 act as dehydrating agent?
H2SO4 acts as a dehydrating agent because it is a strong acid that can provide protons to other compounds, facilitating dehydration reactions. In the presence of H2SO4, water molecules are removed from organic compounds by protonating hydroxyl groups, leading to the formation of an alkene or other dehydrated product.
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.
How sulphur acts as parasiticide action?
How Sulphur acts as a
What observations are made in the reaction of hexane and concentated sulphuric acid?
In the reaction of hexane with concentrated sulfuric acid, the acid acts as a dehydrating agent and can lead to the formation of alkyl sulfates and alkenes. The reaction may also produce some byproducts like water and sulfur dioxide gas. Heat is usually evolved during the reaction due to its exothermic nature.
