Question

1. List the rules for determining an activity series: 2. What happens when carbonates are treated with acid? Write a reaction. 3. Write the products expected for the following double displacement reactions. Which products are expected to be insoluble in water? Na Cro. + Cuci, — K,CO, + AgCIO -

Answer 1

The activity series? single.displacement reactions only occur when the element that is is doing the replacing is more reactive than the element that is being replaced Therefore it is useful to have a list of elements in order of their relative reactivities. The activity series is a list of elements in deaneasing order of their reactivity. since metals replace other metals, ole hon mentals replace other non metals. Activity series of metals and hydrogen Most reactive Li, Rb, k. least reactive Ba, sr, ca, Ma, Mg, Alto, Cr, Fe, Nishopb, H, M, Hq Ag Au Acthrity series of nonmetals Most nearline Fiel, Broo, IS Least reachine Exo This shows, ing is than zu and both most real live 4 mg + Zn son → more reactive metals are than H MgSon + Zn 19 Zn +2Hee → Znch + H₂ But it Copper is loneer on the table, so can't replace the hydrogen in Hel. m + 2Hcl Mo nealtion
