Question

Consider the balanced equation. CuSO4 + Zn ------> ZnSO4 + Cu If 200.0 g of copper(II) sulfate react with an excess of zinc metal, what is the theoretical yield of copper? 1.253 g 50.72 g 79.63 g 194.3 g

Answer 1

can u first find the mole of CuSO4?

Answer 2

first thing for u to do is find mole of CuSO4
u have mass and u can find Mr from periodic table
so find mole

Answer 3

1.25 mols

Answer 4

cool so now do u see that ratio between CuSO4 and Zn is same? 1:1

Answer 5

BUT Zn is in excess so that means CuSO4 is limiting reagent right?

Answer 6

so the answer is a? I have a bunch of quesitons i need help with can you help me somewhere

Answer 7

i'm still confused

Answer 8

no wait

Answer 9

how did u find that its A?

Answer 10

i got confused

Answer 11

I need to know the answer I only have 2 more minutes to turn this in

Answer 12

hhh look the ration between CuSO4 and Cu is 1:1 so means mole is same
mass= mole * Mr

Answer 13

1.25* 63=

Answer 14

where do you get the 63 from

Answer 15

1.25*63.5*

Answer 16

63.5 is Mr of Cu

Answer 17

u wanna find mass of Cu right?

Answer 18

still kinda lost but thank you i have more problems can you help me with?

Answer 19

lets see

Answer 20

open new question for that

Answer 21

kk

Answer 22
