Question

what mass of sodium chloride is produced when chlorine reacts with 0.29 g of sodium iodide

Answer 1

what have you got as your reaction equation?

Answer 2

\[2NaI+Cl2\rightarrow2NaCl+I2\]

Answer 3

Is it in this way?

Answer 4

if it's right then:
Na=23
I=127
0.29/(127+23)= how many mole of NaI we've got, which = the mole of NaCl

Answer 5

then : ?mole x (23+35)= the mass of NaCl you get

Answer 6

That's correct. Once you have your balanced equation, use dimensional analysis to convert from grams NaI -> mols NaI -> mols NaCl -> grams of NaCl

Answer 7

Hi thanks everybody - HOW DO YOU GET A BALANCED EQUATION!?

Answer 8

it counts on a bit of experience, take this one for example, I haven't met this equation before , but I inferred from your posting

Answer 9

you have to find out the elements and compounds of the equation

Answer 10

in this case, the question says Cl2 reacts with NaI
and it also says we get NaCl after reacting

Answer 11

then, what's left?
It's "I"
and I always exists in this way : I2
so we got the equation

Answer 12

then we gonna balance it,
this is a simple case, you can find more examples to practice
in this case
