Question

What does it mean if element A is higher than element B on the activity series?A.B will replace A in a single-replacement reaction.B.A will replace B in a combination reaction.C.A will replace B in a single-replacement reaction.D.B will replace A in a decomposition reaction.

Answer 1

C

Step-by-step explanation

A higher ranked element in the activity series is more reactive in a single replacement reaction. We predict a single replacement reaction will occur when a less reactive element can be replaced by a more reactive element in a compound. Therefore since A is more reactive, it will replace B in a single replacement reaction.
