Balance the equation 7 please and answer 8 thank youuu
7. Silver (Ag) reacts with cyanide (CN-) and oxygen (O₂) to make silver (I) cyanide (Ag(CN)2¯); solution pH=9. Hint: Ag(CN)2 is not the only product of this reaction... what else might you expect in aqueous solution? 8. The reaction I + Cr₂O7²- → I2(s) + Cr³+ Takes place in acidic solution. If the sources of I and Cr₂O72- are KI and Na2Cr2O7, how many grams of KI are needed to completely react with 10.0 g Na₂Cr₂O7?
