A sample of gas contains 0.1400 mol of C2H4 (g) and 0.1400 mol of Br2 (g) and occupies a volume of 17.3 L. The following reaction takes place: C2H4(g) +Br(g) => CH2BrCH2Br(g)

Calculate the volume of the sample after each reaction takes place, assuming that the temperature and the pressure remain constant.

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
