Answer:
Explanation:
2AgNO₃ + Sn ⇄ Sn( NO₃)₂ + 2Ag
Ag⁺/Ag = .80 V
Sn⁺²/Sn = - .14 V
Hence Ag will be reduced and Sn will be oxidised . Hence the reaction will take place . YES .
2 ) 2 electrons are transferred .
3 )
2Ag⁺ + 2e = 2Ag
Sn = Sn⁺² + 2e
---------------------------
2Ag⁺ + Sn = Sn⁺² + 2Ag .
An example of a physical change is the process of tempering steel to form a knife blade.
physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
<span>Chlorine has 7 valence electrons, but in the diagram, there are 2 chlorine atom making there a total of 14 valence electrons. There are 2 valence electrons in between the two atoms. There are 6 valence electrons around the outside of each individual chlorine atom. The electrons are arranged in groups of two around the outside of each atom.</span>
