For which type if reaction must you use an activity series to predict the results
Paha777 [63]

Single replacement or single displacement reactions

Explanation:

In a single replacement or displacement reaction, the activity series is useful in predicting whether the reaction will take place or not.

  • In this reaction type, one substance is replacing another.

                 C + DE → CD + E

  • The relative positions of the two elements in the activity series provides the driving force for the single replacement reaction.
  • An element high up in the series will displace one that is lower in the series because it is more reactive.

Which to which! Ahhhh.
jarptica [38.1K]

Answer:

1.a

2. b

Explanation:

Distillation is a process whereby a mixture of liquids having different vapor pressures is separated into its components. At first one might think that this would be quite simple: if you have a solution consisting of liquid A that boils at 50°C and liquid B with a boiling point of 90°C, all that would be necessary would be to heat the mixture to some temperature between these two values; this would boil off all the A (whose vapor could then be condensed back into pure liquid A), leaving pure liquid B in the pot. But that overlooks that fact that these liquids will have substantial vapor pressures at all temperatures, not only at their boiling points.
