If 90.0 grams of ethane reacted with excess chlorine, how many grams of dicarbon hexachloride would form

What best discribes the relationship between wavelength and frequency in a electromagnetic wave

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?
