Vedclass · Answer

(C) Vulcanization is a chemical process used to improve the physical properties of natural rubber. In this process,natural rubber is heated with $S$ (sulfur) at a temperature range of $140^{\circ}C$ to $160^{\circ}C$. The addition of sulfur creates cross-links between the polymer chains of rubber,which makes the rubber harder,more durable,and resistant to heat and wear. Therefore,the correct non-metal used is sulfur.

$1. \text{Sulphurous acid}$	$p. H_{3}PO_{4}$
$2. \text{Sulphuric acid}$	$q. H_{2}S_{2}O_{7}$
$3. \text{Oleum}$	$r. H_{2}SO_{3}$
$4. \text{Phosphoric acid}$	$s. H_{2}SO_{4}$
