Iodine is prepared both in the laboratory and commercially by adding Cl2(g)to an aqueous solution containing sodium iodide.2NaI(aq)+Cl2(g)⟶I2(s)+2NaCl( aq)How many grams of sodium iodide, NaI, must be used to produce 48.8 g of iodine, I2?

Hello there!

As you know, the products and reactants in a chemical reaction must be equal. Let's review the mole ratio for sodium iodide and iodine:

                                       x      =     y

                                       2              1

                                       x      =     48.8g

                                       2              1

                    1x = (48.8g *2)

                    1x = 97.6g

I hope I helped. :)

hope this !

explanation:

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
