According to the activity series, which of the following single replacement reactions will take place? a. licl + k yields kcl + li b. 2 albr3 + 3mg yields 3mgbr2 + 2al c. pb(no3)2 + 2cu yields 2cuno3 + pb d. cacl2 + 2na yields 2nacl + ca

The correct options are a, b and d.

Explanation:

Single displacement reaction is a type of chemical reaction in which a more reactive metal displaces a less reactive metal from its reaction. Equation for this reaction follows:

Metal A is more reactive than Metal B.

For the given options:

Option a: This reaction is a type of single displacement reaction because potassium is more reactive than lithium.

Option b: This reaction is a type of single displacement reaction because Magnesium is more reactive than Aluminium.

Option c: This reaction will not yield any product because copper is less reactive than lead.

Option d: This reaction is a type of single displacement reaction because Sodium is more reactive than Calcium.

Hence, the correct options are a, b and d.

i just learnt this recently but i need to look through my notes again

there is none because earth is stationary and flat.
