K^+ + I^- -> KI (s)
Because kcl, NaCl & naI are aq so they're split apart & KI is a solid so it stays together, then you just cross out the similar ions.
Because it’s the closest part of the earth to the sun. Basically the sun’s rays hit there more than anywhere else.
Answer:
a. 4, b. 6, c. 4, d. 2
Explanation:
The coordination number (CN) of a complex of a compound is the number of bonds that a metallic ion does with the binders, which can be equal or not.
a. The metallic ion is the iron (Fe), and it's bonded to 2 gly and 2 H2O, thus, CN = 4.
b. EDTA is a hexadentate molecule, thus, it forms 6 bonds with the metal Cr, and CN = 6.
c. The metal is Pt, which has 4 bonds with NH3, thus CN = 4.
d. The metal is Ag, which forms 2 bonds with NH3. NO3 is bonded with the structure and not with the metal. Thus, CN = 2.
Energy is released and mass is reduced
b. .Silver has a lower activity than hydrogen and cannot replace it
Explanation:
The reaction between silver and water cannot proceed because Ag has a lower activity than hydrogen in water.
H₂O + Ag → no reaction
- This reaction is referred to as as single displacement reaction.
- In this kind of reaction, one specie replaces another.
- The replacement of a metallic ion in solution by a metal atom higher in the activity series is the driving force for this reaction.
- Hydrogen is higher than silver and the activity series and will not be displaced by it.
- Therefore, no reaction will occur.
