Question

Sulphur burns in oxygen to form sulphur dioxide. The properties of sulphur dioxide are:
A. Totally different from sulphur and oxygen
B. Similar to sulphur
C. Similar to oxygen
D. More similar to sulphur than oxygen

Answer 1

Hint: In any chemical change, the properties of chemical compounds formed due to the chemical reaction, is completely changed. This happens due to change in chemical properties. There is formation of new bonds in products and breakage of older bonds.

Complete step by step answer:
If sulphur burn in oxygen to form sulphur dioxide i.e.$S{O_2}$ then sulphur dioxide forms have totally different properties from sulphur and oxygen. This is because during the chemical reaction there is change observed in chemical properties and chemical properties are those in which changes are because of formation of new bonds and breakage of old bonds. During the formation of sulphur dioxide from sulphur and oxygen, the reactant may go through different modification and change in energy as follows.
${S_8}(s) + 8{O_2}(g) \to 8S{O_2}(g)$
Since here sulphur exists in solid form and oxygen and sulphur dioxide exist in gaseous form. Sulphur dioxide is liquefied at room temperature at 2 atmospheric pressure and having acidic nature and non-supporter of combustion. Sulphur dioxide has reduced action and also has bleaching action and also acts as a mild oxidising agent.
Thus, the correct option is A. Totally different from sulphur and oxygen.

Note:
Sulphur dioxide is also known by different names such as sulphurous anhydride and sulphur (IV) oxide. Liquid sulphur dioxide is used as a refrigerant and as a solvent to dissolve a number of organic and inorganic chemicals. It is also used in refining the petroleum and sugarcane juice.
