What is the polyatamic ion of thiosulfate

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

At stp, which substance is the best conductor of electricity? a. nitrogen b. neon c. sulfur d. silver
