The following observations involving metals A, B, C, and D were made:
(1) When a strip of A is placed in a solution of B2β +β ions, no reaction observed.
(2) Similarly, A plus C+β β ions produce no reaction.
(3) When a strip of D is placed in a solution of C+β β ions, black metallic C deposits on the surface
of D, and the(aq)e solution tests positively for D2β +β ions.
(4) When a bar of B is placed in a solution of D2β +β ions, metallic D appears on the surface of B
and B2β +β ions are found in the solution.
Arrange the ions A+β β, B2β +β, C+β β, and D2β +β in order of their ability to attract electrons. On top, place
the ion that best attracts electrons

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
