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?

Use the half-reactions of the reaction au(oh)3 + hi -> au +i2 +h2o to answer the questions

If a molecule is polar, what kind of bonds will it have
