Beryllium metal reacts with chlorine gas to produce beryllium chloride (BeCl₂). Given the following diagram of available beryllium atoms and chlorine molecules in a reaction flask, identify the excess reagent and how many atoms/molecules of reactant remain at the end of the reaction. A)Excess reagent: chlorine; Molecules remaining: one B)Excess reagent: beryllium; Atoms remaining: one C)Excess reagent: chlorine; Molecules remaining: two D)Excess reagent: beryllium; Atoms remaining: two E)There is no excess reagent in this reaction.

Question

Quizplus · Accepted Answer

There are two beryllium atoms and one chlorine molecule available, indicating that beryllium is the limiting reagent and chlorine is in excess. Therefore, there will be one beryllium atom remaining at the end of the reaction. The chlorine molecule will completely react with the available beryllium atoms to produce one molecule of beryllium chloride.
