Question

What type of reaction is Pb(NO3)2+KI-->KNO3+PbI2?

Answer 1

do you know what the 5 general types of reactions are?

Answer 2

Synthesis


Single-Replacement


Double-Replacement


Combustion

Answer 3

there's also decomposition, which looks just like a synthesis run backwards. This reaction is one of those 5

Answer 4

can you tell me which one?

Answer 5

i bet you could figure it out if you tried ;-)

Answer 6

each type of reaction has a certain "look".

Answer 7

well i can't ive spent an hour working on this one problem

Answer 8

\(Pb(NO_3)_2\) and \(KI\) are both ionic compounds. The products \(KNO_3\) and \(PbI_2\) are also ionic compounds, but what has happened to the "partnerships"?

Answer 9

we havent learned that yet

Answer 10

look at the formulas of the pieces, that's all you need to do

Answer 11

i have and i still dont understand

Answer 12

as a reactant, \(Pb^{+2}\) is partnered with \(NO_3^{-1}\), and \(K^{+1}\) is partnered with \(I^{-1}\). As the PRODUCTS, what has happened to the partners?

Answer 13

they got put together

Answer 14

look at who the lead is combined with as a reactant (on the left side of the arrow), and who it is combined with as a product (on the right side)

Answer 15

whyyyyy cant you just tell me

Answer 16

because i'm teaching you to recognize patterns so you can do it yourself

Answer 17

dude just answer the question i swear to my mom

Answer 18

okay tell me again then

Answer 19

^^scroll up and check again

Answer 20

im going to smack you.

Answer 21

each formula is made of a pair of ions. 2 pairs of ions make the 2 reactants, and 2 pairs of ions make the 2 products. What kind of reaction looks exactly like that?

Answer 22

i guessed. its too late

Answer 23

oh well. maybe you can work a little harder next time and not give in to instant gratification and perhaps learn something

Answer 24

good luck though, I have class to teach
