Silicones can be oils or rubber-like materials depending on . Select one: A. the silicon-to-oxygen ratio B. the length of the chain and degree of cross-linking C. the percentage of carbon in the chain D. the oxidation state of silicon in the chain E. the percentage of sulfur in the chain

B-- the length of the chain and degree of cross-linking.

Explanation: Silicones can be oils or rubber-like materials depending on ___the length of the chain and degree of cross-linking.

Silicone rubber is an elastomer which is composed of silicone containing silicon together with carbon, hydrogen, and oxygen. silicone rubber can be found in a wide variety of products because of its ability to withstand very high temperatures and pressures. eg cooking and food storage products; clothing apparels , automotive devices etc   while
