Consider four beakers labeled A, B, C, and D, each containing an aqueous solution and a solid piece of metal. Identity the beakers m which a chemical reaction will occur and those in which no reaction will occur. a. Mn(s) + Ca(NO3)2(aq) b. KOH(aq) + Fe(s) c. Pt(NO3)2(aq) + Cu(s)d. Cr(s) + H2SO4(aq)Drag each item to the correct bin. Consider the following data for five hypothetical element: Q, W, X, Y, and Z. Rank the elements from most reactive to least reactive. Place the element symbol from most to least reactive. To rank items as equivalent, overlap them. Use the following reactions to arrange the elements A, B, C, and D in order of their rodox reactivity from most reactive to least reactive. A + D+ rightarrow A+ + D C+ + D rightarrow C + D+ B+ + D rightarrow B + D+ B + C+ rightarrow B+ + C Rank from most reactive to least reactive. To rank items as equivalent overlap them.
