Question

USE LETTERS FOR ANSWERS, NO NEED TO EXPLAIN

a) Substitute symbols and formulas for words.
b) Predict the products. If no reaction occurs, write “NR” after the --> sign. c) Include abbreviations for the physical state.
d) Write out and balance the equation.

6. Mercury is poured into an aqueous solution of zinc nitrate.

7. Solutions of potassium iodide and lead (II) nitrate are mixed. The resulting lead compound is a precipitate.


thank you! :)

Answer 1

Ok:

Step-by-step explanation:

6a)
`Hg + Zn(NO_3)_2\\`

b) NR

c)
`Hg_((l)) + Zn(NO_3)_2 {(aq)}=> NR`

d) Welp, no reaction so i don't know.

7a)
`KI + Pb(NO_3)_2`

b)
`PbI_2 + KNO_3`

c) All are aqeuous except for PbI2 which is solid

d)
`2KI _((aq))+ Pb(NO_3)_2_((aq)) => PbI_2_((s)) + 2KNO_3_((aq))`

Check if that is ok or if my work has any issues :).
