Make sure that the hose is fitted tightly into the reaction vessel and that the trash bag is firmly affixed to the other end. It dissolves in water, ethanol, diethyl ether, carbon disulfide, pyridine, and sulfur dioxide. (b) A sodium cation (Na+) has lost an electron, so it has one more proton (11) than electrons (10), giving it an overall positive charge, signified by a superscripted plus sign. Dxygen copolyesters are widely used in the production of packaging materials, automotive parts, and medical devices due to their excellent properties such as heat resistance, chemical resistance, and enhanced durability. reducing agent should tell us something about the relative
