Answer 11

oh ok

Answer 12

@abmon can u please ?

Answer 13

For sure :) @Abhisar and @superhelp101 In the first Reaction a cation replacement occured. In the Last Reaction a anion replacement Manganese ion stays the same from +4 to +4 so as magnesium +2.
MgCl2 + Li2CO3 --> MgCO3 + LiCl
A double replacement occured both cation and anion replacement
Li+2-->Li+
2Cl-2-->Cl-

Answer 14

thank you!

Answer 15

@Abmon98 using you explaination would you say that the answer the second option?

Answer 16

yes thats right :) @superhelp101
