correct decreasing reactivity order for metal in malaysia

If metal X is lower then metal Y in the activity series, then …

2014/8/27· In order to determine whether a single replacement (displacement) reaction will occur, we look at the activity series for metals. If metal X will replace (displace) metal Y, then metal X must be above metal Y in the activity series for metals. If metal X is lower than metal Y, there will be no reaction. For example, copper (Cu) is higher on the reactivity series than silver (Ag). Therefore
