Because ethylene dibromide, a chemical used to fumigate grain, was blamed for the high rate of nerve damage suffered by people who work in grain-processing plants, many such plants switched to other chemical fumigants two years ago. since then, however, the percentage of workers at these plants who were newly diagnosed with nerve damage has not dropped significantly. therefore, either ethylene dibromide was wrongly blamed or else the new chemicals also cause nerve damage.
which of the following is an assumption on which the argument depends?
(a) if the new chemicals cause nerve damage, the nerve damage caused would be different from any nerve damage that ethylene dibromide may cause.
(b) there are no chemical fumigants that are completely safe for workers in grain processing plants.
(c) if ethylene dibromide causes nerve damage, it does not take two years or longer for that damage to become detectable.
(d) workers at grain-processing plants typically continue to work there even after being diagnosed with nerve damage.
(e) workers at grain-processing plants that still use ethylene dibromide continue to have a high rate of nerve damage.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

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?
