Answer 3

look carefully at each reaction

Answer 4

where do you see only 1 replacing happening?

Answer 5

ok so could it be B?

Answer 6

there are 2 options you can cancel out straightaway

Answer 7

look at B once again
what is being replaced by what?

Answer 8

it is a A double replacement reaction

Answer 9

nope

Answer 10

in A how can you see anything being replaced if they are is 1 product at the end?

Answer 11

i am so confused.. i thought we were talking about option B?

Answer 12

Option B is double displacement
option A is not any kind of displacement

Answer 13

look
for example A and a compound BC
A+ BC---> BA+ C
do you see it?
C is being displaced by A
this is single displacement

Answer 14

ohh i see now! i the correct option is C?

Answer 15

nope A and C are actually the options you can cancel out
If there is any kind of displacement reaction we will ALWAYS have MORE THAN 1 PRODUCT
